Product details
Overview
AD9625BBPZ-2.6 from Analog Devices is a 12-bit, 2.6 GSPS monolithic analog-to-digital converter optimized for direct RF sampling in the second Nyquist zone. It features 3.2 GHz analog input bandwidth, −149.5 dBFS/Hz noise spectral density at 2.6 GSPS, and JESD204B subclass 1 serial output supporting 6.5 Gbps lane rate. It serves as the front-end digitizer in wideband radar receivers and electronic warfare systems.
For engineers reviewing the AD9625BBPZ-2.6 datasheet, AD9625BBPZ-2.6 pinout, AD9625BBPZ-2.6 application, or AD9625BBPZ-2.6 equivalent, key selection criteria include SFDR performance at 1.8 GHz (75.4 dBc), dual decimation filters with 10-bit NCOs, differential clock and SYSREF± inputs for multichip synchronization, and guaranteed no missing codes across industrial temperature range (−40°C to +85°C).
Technical Context
The AD9625BBPZ-2.6 implements a high-speed pipeline ADC architecture with integrated digital downconverters (DDCs) offering decimate-by-8 or decimate-by-16 filtering and numerically controlled oscillators (NCOs) for frequency translation. Its analog input stage supports 1.2 V p-p differential full-scale range and operates up to 3.2 GHz full-power bandwidth.
Digital output conforms to JESD204B subclass 1 with configurable 6- or 8-lane CML interface, enabling deterministic latency and multidevice synchronization via SYSREF±. Clock management includes aperture jitter of 80 fs rms and 226-cycle pipeline latency in eight-lane mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9680BCBZ-500 | 14-bit, 500 MSPS; lower sampling rate but higher ENOB (7.9 bits @ 1800 MHz vs. 8.9 bits for AD9625BBPZ-2.6) | Better suited for high-resolution narrowband applications (e.g., precision instrumentation), not wideband RF capture. | Select when SNR > SFDR is prioritized and 2.6 GSPS is unnecessary. |
| ADC12DJ3200IRSBT | 12-bit, dual-channel 3.2 GSPS; JESD204C support; higher power (5.3 W); 2.5 V supply only (no 1.3 V rail) | Enables time-interleaved sampling for wider instantaneous bandwidth; requires different power delivery and layout. | Choose for next-generation systems needing >2.6 GSPS or JESD204C migration path. |
Compared with AD9625BBPZ-2.6, AD9680BCBZ-500 trades raw speed for resolution in bandwidth-constrained scenarios, while ADC12DJ3200IRSBT extends sample rate and adds dual-channel capability at the cost of increased power and supply complexity-neither offers identical 2.6 GSPS + JESD204B subclass 1 + 3.2 GHz bandwidth combination.

FAQ
What is the maximum analog input frequency supported by AD9625BBPZ-2.6?
The AD9625BBPZ-2.6 supports analog input frequencies up to 3.2 GHz full-power bandwidth, enabling direct sampling of signals in the second Nyquist zone (e.g., 1–2 GHz RF carriers). This specification is measured with internal termination and applies across the industrial temperature range (−40°C to +85°C).
Does AD9625BBPZ-2.6 support JESD204B subclass 1 synchronization?
Yes, AD9625BBPZ-2.6 fully supports JESD204B subclass 1, including deterministic latency and multidevice synchronization using SYSREF±. The device requires SYSREF± edges aligned to the rising clock edge with +200 ps setup and −100 ps hold time, enabling coherent operation in phased-array radar systems.
What power supplies are required for AD9625BBPZ-2.6 operation?
AD9625BBPZ-2.6 requires three independent voltage rails: AVDD1/DRVDD1/DVDD1 = 1.3 V (±30 mV), AVDD2/DRVDD2/DVDD2 = 2.5 V (±100 mV), and DVDDIO/SPI_VDDIO = 2.5 V or 3.3 V. Total power dissipation is 4.3 W in eight-lane mode at 2.6 GSPS, demanding careful thermal design on 4-layer PCBs.
Can AD9625BBPZ-2.6 perform digital downconversion internally?
Yes, AD9625BBPZ-2.6 integrates two independent digital downconverters (DDCs) with 10-bit numerically controlled oscillators (NCOs), supporting decimate-by-8 or decimate-by-16 filtering. This enables real-time frequency translation and channelization without external FPGA logic, reducing system latency and resource usage.
What is the conversion error rate specification for AD9625BBPZ-2.6?
The AD9625BBPZ-2.6 guarantees a conversion error rate of less than 10⁻¹⁵, meaning fewer than one erroneous sample per 10¹⁵ conversions. This ultra-low error rate ensures data integrity in mission-critical applications such as radar target tracking and electronic surveillance where undetected bit errors are unacceptable.
