Ultra-High-Speed Dual 12-Bit Pipeline ADC Architecture for Phased Array Radar Systems

The dual 12-bit ADC cores digitize at 250 MSPS through a monolithic sampling architecture with integrated sample-and-hold and voltage reference on the same silicon die. The 400 MHz full-power bandwidth represents a significant advancement over previous generations of 12-bit ADCs, enabling direct IF sampling of wideband radar returns and electronic warfare signals up to 400 MHz without the need for intermediate frequency conversion stages. This capability reduces system complexity, component count, and potential signal degradation associated with multi-stage downconversion architectures in phased array radar systems where receiver modules are distributed across large antenna apertures. Differential analog inputs with programmable voltage range (1.4 V p-p to 2.0 V p-p) provide excellent immunity to common-mode noise and ground loops while offering flexibility to optimize dynamic range for different signal levels encountered in radar and EW applications. The proprietary differential input architecture maintains excellent SNR performance for input frequencies up to 400 MHz, which is critical for preserving signal fidelity in wideband electronic warfare receivers that must capture weak signals in the presence of strong interference.

The AD9613 architecture provides excellent linearity characteristics with differential nonlinearity (DNL) of ±0.5 LSB and integral nonlinearity (INL) of ±0.8 LSB typical. This linearity ensures consistent conversion accuracy across the entire input range, critical for radar systems where precise amplitude measurement determines target detection thresholds and range accuracy. The effective number of bits (ENOB) of 11.1 at 185 MHz input frequency provides usable resolution close to the theoretical 12-bit limit at ultra-high input frequencies, enabling detailed signal characterization in electronic warfare applications where subtle signal variations indicate sophisticated modulation schemes or low-probability-of-intercept signals. The 86 dBc SFDR at 185 MHz ensures that spurious tones remain well below the radar system’s dynamic range requirements, preventing false target detection or signal degradation in sensitive EW receivers operating in congested electromagnetic environments. The 95 dB channel isolation and crosstalk specification is particularly important for phased array radar systems where multiple AD9613 devices are densely packed in receiver modules, ensuring minimal interference between adjacent channels that could degrade beamforming accuracy.

Integrated Reference and Advanced System Integration Features for Avionics Applications

The integrated voltage reference represents a significant architectural advancement over traditional high-speed ADC designs, eliminating the need for external reference components while maintaining excellent accuracy across temperature variations. The internal reference provides a stable 1.75 V full-scale input range with typical reference voltage accuracy of ±10 mV offset error and ±4% gain error, which is sufficient for most aerospace applications requiring high dynamic range but not requiring calibration-grade precision. This integration eliminates the need for external voltage reference ICs, associated filtering capacitors, and PCB routing complexity, reducing component count, board space requirements, and potential failure points in mission-critical avionics systems. The duty cycle stabilizer (DCS) compensates for variations in the ADC clock duty cycle, which is critical for maintaining performance in systems where clock jitter and duty cycle variations can degrade SNR and SFDR at ultra-high sampling rates. The DCS ensures consistent performance across the industrial temperature range without requiring precise clock source conditioning, simplifying clock distribution network design in phased array radar systems where clock signals are distributed to dozens or hundreds of receiver modules.

Beyond the reference and DCS, the AD9613 incorporates flexible power management features that optimize system-level power consumption in radar and EW applications. Flexible power-down options allow significant power savings when ADC channels are not actively digitizing, which is critical for multi-mode radar systems that switch between different operational modes based on threat scenarios. Standby power consumption of 90 mW and power-down power consumption of 10 mW represent substantial reductions compared to the 770 mW typical operating power consumption, enabling duty-cycled operation in energy-constrained platforms such as unmanned aerial vehicles (UAVs) and portable tactical systems. The integer 1-to-8 input clock divider (625 MHz maximum input) enables flexible clock architecture design while maintaining low jitter performance through the on-chip duty cycle stabilizer, allowing system designers to optimize clock distribution networks based on available clock sources and jitter performance requirements. Fast overrange and threshold detect features provide early warning of signal clipping or threshold crossing events, enabling automatic gain control (AGC) systems to respond rapidly to changing signal environments in dynamic EW scenarios.

LVDS Digital Interface and Multi-Device Synchronization for Phased Array Radar

The AD9613 provides 12-bit data from each of the dual ADC cores through two external LVDS (ANSI-644 compatible) output ports, offering excellent noise immunity and reduced power consumption compared to CMOS outputs. LVDS technology is particularly advantageous for avionics systems where high-speed data paths run through long traces in backplanes between multiple processing boards, as the differential signaling provides excellent immunity to common-mode noise and ground potential differences that inevitably exist in complex avionics chassis with distributed power and ground references. The LVDS output data can be formatted either as interleaved (where both channels’ data are time-multiplexed on a single port) or channel multiplexed (where each channel’s data is output on a separate port), providing system designers with flexibility to optimize interface timing and FPGA resource utilization based on specific application requirements. The SYNC input enables synchronization of multiple AD9613 devices for phased array radar systems requiring dozens or hundreds of coherent channels, which is essential for maintaining phase coherence across the entire antenna aperture for accurate beamforming and direction finding.

A dedicated data clock output (DCO±) provides precise timing for FPGA capture logic, while programmable clock and data alignment features enable optimization of timing relationships for different FPGA architectures and interface requirements. The serial port interface (SPI-compatible) provides comprehensive control over ADC configuration and operation, including data format selection (twos complement or offset binary), power-down mode activation, gain adjustment, and test pattern generation. This SPI control capability eliminates the need for hardware configuration pins that would increase package size and routing complexity, enabling the 64-lead LFCSP package despite the rich feature set. The 3-pin, 1.8 V SPI port supports register programming and register readback, enabling system monitoring and diagnostic capabilities that are critical for mission-critical aerospace applications where health monitoring and fault detection are essential for system reliability. Pin compatibility with the AD9643 (14-bit dual ADC), AD6649, and AD6643 provides a migration path for system upgrades without requiring complete PCB redesign, which is valuable for aerospace programs with long lifecycles and evolutionary upgrade requirements.

For applications requiring maximum resolution, the AD9643 provides 14-bit performance with 70.5 dBFS SNR and 85 dBc SFDR at 185 MHz, compared to the AD9613’s 69.6 dBFS SNR and 86 dBc SFDR at the same input frequency. The pin compatibility allows direct substitution on the same PCB layout, enabling product differentiation or performance upgrades during the product lifecycle without requiring routing changes or new PCB designs. Power consumption differs slightly between the two devices, with the AD9613 consuming 770 mW typical at 250 MSPS compared to the AD9643’s 790 mW at the same sampling rate, representing approximately 2.5% power savings for the 12-bit version. For applications where the AD9613’s 12-bit resolution provides adequate performance for radar and EW requirements, the cost-optimized architecture provides value while maintaining similar dynamic range characteristics and system-level features.

What Is the Power Consumption of AD9613BCPZ-250 at 250 MSPS?

The device consumes 770 mW typical at 250 MSPS in LVDS mode with the 1.8 V analog and digital supplies at nominal voltages, operating dual ADC cores simultaneously. This power consumption breaks down to approximately 252 mA to 275 mA from the AVDD supply (1.8 V analog) and 176 mA to 210 mA from the DRVDD supply (1.8 V digital output drivers), totaling 428 mA to 485 mA of current draw at typical operating conditions. The 770 mW typical power consumption represents the power draw when both ADC cores are actively digitizing at maximum sampling rate, which is relevant for continuous wave radar systems or wideband EW receivers that require uninterrupted signal capture. For applications that do not require continuous operation, flexible power-down options enable significant power savings. Standby power consumption is 90 mW, and full power-down mode reduces power consumption to just 10 mW, enabling duty-cycled operation in energy-constrained platforms such as unmanned aerial vehicles (UAVs) and portable tactical systems. The single 1.8 V supply operation for both analog and digital sections reduces power distribution complexity and eliminates the need for separate voltage regulators for analog and digital domains.

Does AD9613BCPZ-250 Support On-Chip Reference Voltage?

Yes, this device features an internal ADC voltage reference that eliminates the need for external reference components in most applications. The internal reference provides a stable 1.75 V full-scale input range with typical reference voltage accuracy of ±10 mV offset error and ±4% gain error, which is sufficient for most aerospace applications requiring high dynamic range but not requiring calibration-grade precision. This integration eliminates the need for external voltage reference ICs, associated filtering capacitors, and PCB routing complexity, reducing component count, board space requirements, and potential failure points in mission-critical avionics systems. The integrated reference accuracy meets the requirements of most radar and EW applications where signal processing gain variations can be calibrated out digitally. For applications requiring calibration-grade precision or specific reference voltage values, external reference mode can be implemented, though this is not typically required for the AD9613’s intended aerospace and defense applications. The reference voltage stability across the industrial temperature range of −40°C to +85°C is ensured by internal temperature compensation circuitry, maintaining consistent performance in harsh avionics environments where temperature variations can be extreme.

How Do I Synchronize Multiple AD9613BCPZ-250 Devices for Phased Array Radar Systems?

The AD9613 includes a SYNC input that enables synchronization of multiple devices for phased array radar systems requiring dozens or hundreds of coherent channels. The SYNC input is CMOS/LVDS compatible with internal bias at 0.9 V and an input voltage range from AGND to AVDD, accepting both CMOS and LVDS level signals for maximum flexibility in clock distribution network design. Synchronization is achieved by simultaneously asserting the SYNC input on all AD9613 devices in the array, which resets internal timing circuits and aligns the sampling phase of all ADCs to the same edge of the distributed clock. This synchronization capability is essential for maintaining phase coherence across the entire antenna aperture for accurate beamforming and direction finding in phased array radar systems. The combined use of SYNC input and integer 1-to-8 clock divider enables flexible clock distribution architectures while maintaining phase coherence across large antenna arrays with hundreds of receiver modules. System designers should ensure careful clock distribution network design to minimize skew between different AD9613 devices, as clock skew directly translates to phase errors that degrade beamforming accuracy. The 95 dB channel isolation specification ensures minimal crosstalk between adjacent channels in densely packed receiver modules, which is particularly important when multiple AD9613 devices are closely spaced on the same PCB or module.

Can AD9613BCPZ-250 Be Controlled via SPI Serial Port?
