Product details
Overview
AD9689BBPZ-2600 from Analog Devices is a dual-channel, 14-bit, 2.6 GSPS analog-to-digital converter with JESD204B Subclass 1 serial interface, 9 GHz analog input bandwidth, −152 dBFS/Hz noise density at 2.56 GSPS (1.7 V p-p full-scale), and integrated digital downconverters (DDCs) supporting multiband RF receivers in phased-array radar and DOCSIS 3.0 CMTS systems.
For engineers reviewing the AD9689BBPZ-2600 datasheet, AD9689BBPZ-2600 pinout, AD9689BBPZ-2600 application, or AD9689BBPZ-2600 equivalent, key selection criteria include deterministic latency control via SYSREF±, programmable NCO switching for band selection, JESD204B lane rate scalability up to 16 Gbps, and dual-channel SNR/SFDR performance at RF frequencies up to 5.53 GHz.
Technical Context
The AD9689BBPZ-2600 implements two independent pipelined ADC cores with on-chip buffer and sample-and-hold, each feeding four cascaded DDCs-each containing a 48-bit NCO, decimation filters, and complex-to-real conversion logic. It supports phase-coherent NCO switching via GPIO pins and configurable decimation rates across up to four output channels.
JESD204B Subclass 1 operation enables deterministic latency with LMFC alignment, synchronized across multiple devices using SYSREF± and SYNCINB± inputs. The device uses LVDS/LVPECL clock and reference inputs, SST differential serial outputs, and CMOS SPI control (100 MHz writes / 50 MHz reads) for register configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9208BCPZ-3000 | Higher 3.0 GSPS max sample rate; identical pin/package/feature set but optimized for 3 GHz operation; higher power (3.7 W typical). | Better suited for future-proofed 5G FR1 massive MIMO baseband units requiring >2.6 GSPS sustained sampling. | Select when system clock architecture supports ≥3 GHz sampling and thermal budget allows +0.6 W dissipation. |
| ADC12DJ3200IRSBT | Texas Instruments part; dual 12-bit, 3.2 GSPS; JESD204C capable; lower resolution but higher sample rate and integrated clock synthesizer. | Preferred for JESD204C-based systems or where on-chip PLL eliminates external clock conditioner; trades ENOB for raw speed. | Choose when migrating to JESD204C infrastructure or when 12-bit resolution suffices for wideband noise floor-limited applications. |
Compared with AD9689BBPZ-2600, AD9208BCPZ-3000 offers higher sample rate at the cost of increased power and reduced thermal margin, while ADC12DJ3200IRSBT provides JESD204C readiness and integrated clocking but sacrifices 2 bits of resolution-making AD9689BBPZ-2600 optimal for legacy JESD204B systems demanding 14-bit fidelity at 2.6 GSPS.

FAQ
What is the maximum analog input frequency supported by the AD9689BBPZ-2600?
The AD9689BBPZ-2600 supports full-power analog input signals up to 5 GHz, enabled by its 9 GHz −3 dB analog input bandwidth. Performance specifications including SNR and SFDR are guaranteed up to 5.53 GHz under specific full-scale voltage (1.1 V p-p) and decimation conditions, as verified in Table 2 of the Rev. A datasheet.
Does the AD9689BBPZ-2600 support JESD204B Subclass 0 or only Subclass 1?
The AD9689BBPZ-2600 supports JESD204B Subclass 1 exclusively. Its deterministic latency architecture relies on SYSREF± alignment and LMFC synchronization-features required for multichip coherent sampling in radar and beamforming. Subclass 0 operation is not implemented or characterized for AD9689BBPZ-2600.
How many digital downconverters (DDCs) does the AD9689BBPZ-2600 integrate per channel?
The AD9689BBPZ-2600 integrates four independent digital downconverters per analog channel. Each DDC includes a 48-bit NCO, programmable decimation filters, gain stage, and complex-to-real conversion-allowing simultaneous processing of up to four distinct frequency bands from a single ADC channel.
What power supply voltages does the AD9689BBPZ-2600 require?
The AD9689BBPZ-2600 requires seven distinct supply rails: AVDD1/AVDD1_SR (0.975 V), AVDD2 (1.9 V), AVDD3 (2.5 V), DVDD (0.975 V), DRVDD1 (0.975 V), DRVDD2 (1.9 V), and SPIVDD (1.9 V). All are specified with ±25 mV tolerance and require dedicated low-noise LDO regulation per rail as detailed in the Power Supply Recommendations section (Page 132).
Is the AD9689BBPZ-2600 pin-compatible with any other Analog Devices ADCs?
Yes-the AD9689BBPZ-2600 is pin, package, feature, and memory-map compatible with the AD9208 14-bit, 3.0 GSPS dual ADC. This compatibility enables drop-in migration paths for designs scaling sampling rate beyond 2.6 GSPS, provided thermal and power delivery systems accommodate AD9208's higher 3.7 W typical dissipation.
