ADI AD9172BBPZ

The architectural distinction of the AD9172BBPZ within the AD917x RF DAC family is the channelizer: three independent complex data input channels per DAC, each with its own NCO, gain stage, and interpolation filter, aggregated into a single 12.6 GSPS DAC output. For radar and electronic warfare transmit chain designers, this means a single physical DAC output can simultaneously synthesize carriers at three independently programmable frequencies within the DAC’s output bandwidth, without external power combiners or additional DAC channels. In multiband base station and multi-function radar applications where transmitting on multiple bands simultaneously from a shared aperture is the architecture, the AD9172BBPZ’s channelizer structure eliminates the discrete DAC, combiner, and frequency planning complexity that single-channel RF DAC implementations require.

AD9172BBPZ Architecture: Channelizer DSP and Ultrawide Bandwidth Modes

The three complex input channels per DAC in the AD9172 operate independently, each maintaining its own NCO frequency, gain setting, and interpolation filter configuration. The FPGA feeds baseband I and Q data for each channel on the JESD204B link, and the channelizer aggregates the three upconverted channels into the DAC core at the full 12.6 GSPS rate. The maximum 1.5 GSPS complex data rate per channel supports up to 3 GHz of instantaneous bandwidth per carrier, covering single-channel bandwidths appropriate for wideband radar waveforms. When maximum instantaneous bandwidth across a single carrier is the priority rather than multiband flexibility, the ultrawide bandwidth bypass mode connects the JESD204B data input directly to the DAC core, achieving 3.08 GSPS complex data rate with 16-bit resolution. The on-chip clock multiplier synthesizes the full DAC sample clock from a lower frequency reference, reducing external clocking infrastructure requirements and the jitter contribution of the clock distribution path.

AD9172BBPZ vs AD917x Family: Channelizer Architecture Selection

The AD917x family spans three devices sharing the same core DAC architecture with different channelizer configurations:

The AD9172BBPZ is the correct selection for dual-channel multiband applications requiring three input channels per DAC. For single-channel applications where one RF DAC output is sufficient, the AD9171 reduces the device’s footprint and power. For applications requiring six independent input channels per DAC for the highest multiband flexibility, the AD9173 is the appropriate step up. For programs requiring transmit DAC and receive ADC integration in a single device at higher effective sample rates, the AD9081BBPZ-4D4AC MxFE provides a complete transceiver with four 12 GSPS DAC cores and four 4 GSPS ADC cores. For single-channel direct RF applications with integrated DDS frequency hopping, the AD9164BBCAZ is the relevant alternative.

Frequently Asked Questions (FAQ)

What Is the ADI AD9172BBPZ and How Does Its Channelizer Architecture Work?

The AD9172BBPZ is a dual 16-bit RF DAC supporting up to 12.6 GSPS with three independent bypassable complex input channels per DAC, each with its own NCO, gain stage, and interpolation filter, in a 144-ball 10mm TEBGA tray package rated for –40°C to +85°C. The channelizer aggregates up to three independently frequency-planned carriers into a single DAC output, enabling simultaneous multiband transmission without external combining hardware.

What Is the Difference Between AD9172BBPZ and AD9172BBPZRL?

Both are the same AD9172 dual 16-bit RF DAC with identical electrical specifications. The BBPZ is tray-packaged for prototype and qualification builds; the BBPZRL is tape-and-reel for volume production SMT assembly. Choose BBPZ for lower-quantity prototype and qualification procurement; choose BBPZRL for production volume builds.

How Does the AD9172BBPZ Ultrawide Bandwidth Mode Differ From the Channelizer Mode?

In channelizer mode, the three complex input channels each contribute a narrowband carrier at independent NCO frequencies, aggregated into the 12.6 GSPS DAC output. In ultrawide bandwidth bypass mode, the channelizer is bypassed and the JESD204B data input connects directly to the DAC core, supporting up to 3.08 GSPS complex data rate at 16-bit resolution for maximum instantaneous bandwidth applications where a single wideband carrier is required rather than multiple narrowband carriers.

How Does the AD9172BBPZ Compare to the AD9081BBPZ-4D4AC for Radar Applications?

The AD9081BBPZ-4D4AC integrates four DAC cores at 12 GSPS each alongside four ADC cores at 4 GSPS in a 28 nm MxFE transceiver, providing complete transmit and receive functionality in a single device. The AD9172BBPZ provides two DAC cores at 12.6 GSPS with deeper per-DAC channelizer flexibility of three input channels each, but no integrated receive ADC. Choose the AD9172 for transmit-only or external-receiver architectures where the channelizer flexibility is the priority. Choose the AD9081 for complete transceiver integration.
