Product details
Overview
AD9695BCPZ-625 from Analog Devices is a dual-channel, 14-bit, 625 MSPS analog-to-digital converter with JESD204B Subclass 1 serial output, 2 GHz full-power analog input bandwidth, and integrated digital downconverters (DDCs) per channel. It operates from 0.95 V/1.8 V/2.5 V supplies, delivers 67.2 dBFS SNR at 172.3 MHz input, and supports ultrawideband communications receivers requiring high dynamic range and deterministic latency.
For engineers reviewing the AD9695BCPZ-625 datasheet, AD9695BCPZ-625 pinout, AD9695BCPZ-625 application, or AD9695BCPZ-625 equivalent, this page provides verified specifications, validated pin functions, confirmed DDC architecture details, real-world AGC implementation support via fast detect outputs, and precise supply rail requirements for RF sampling systems.
Technical Context
The AD9695BCPZ-625 implements two independent pipelined ADC cores with on-chip buffer and sample-and-hold, each feeding a dedicated 48-bit NCO-based digital downconverter with programmable decimation filters. Its JESD204B interface supports 1–4 lane configurations with lane rates up to 16 Gbps and deterministic latency enabled by SYSREF± synchronization.
It features dual differential analog inputs (VIN+A/VIN–A and VIN+B/VIN–B), LVDS/LVPECL clock and SYSREF inputs, CMOS control logic (SPI), and four differential JESD204B SERDOUT lanes. Power management includes SPI- or pin-controlled power-down (200 mW) and standby (740 mW) modes across nine supply domains.

FAQ
What is the maximum analog input frequency supported by the AD9695BCPZ-625?
The AD9695BCPZ-625 supports a 2 GHz full-power analog input bandwidth, meaning it maintains specified SNR and SFDR performance up to 2 GHz input frequency. This enables direct sampling of L- and S-band RF signals without analog downconversion. The −3 dB point of the analog input path is confirmed at 2 GHz per the Rev. C datasheet, Page 4.
Does the AD9695BCPZ-625 include an internal voltage reference?
Yes, the AD9695BCPZ-625 integrates a 0.5 V internal voltage reference with ±6 ppm/°C temperature drift (typical), eliminating the need for an external reference IC. This reference is used for ADC core conversion and is accessible via the VREF pin. It is specified in Table 1 (DC Specifications) and detailed in the "Voltage Reference" section (Page 30) of the Rev. C datasheet.
How many JESD204B lanes does the AD9695BCPZ-625 support, and what is the maximum lane rate?
The AD9695BCPZ-625 supports 1, 2, or 4 JESD204B Subclass 1 lanes, with a maximum lane rate of 16 Gbps. Lane count and rate depend on DDC configuration and decimation settings. This flexibility allows optimization between PCB routing density and serializer/deserializer compatibility, as documented in the "JESD204B Overview" section (Page 71) and Table 5 (Switching Specifications).
What is the fast detect latency of the AD9695BCPZ-625, and how is it used in AGC systems?
The AD9695BCPZ-625 provides fast detect outputs (FD_A and FD_B) with a fixed latency of 26 clock cycles, enabling rapid overrange detection for automatic gain control loops. This low-latency indicator allows system-level gain reduction before ADC saturation occurs, critical in burst-mode communications. The function is controlled via Register 0x0245 and described in the "ADC Overrange and Fast Detect" section (Page 34).
What power supply voltages does the AD9695BCPZ-625 require, and how are they allocated?
The AD9695BCPZ-625 requires nine distinct supply rails: AVDD1/AVDD1_SR (0.95 V), AVDD2 (1.8 V), AVDD3 (2.5 V), DVDD (0.95 V), DRVDD1 (0.95 V), DRVDD2 (1.8 V), and SPIVDD (1.8 V). These isolate analog core, reference, digital logic, JESD204B drivers, and SPI interface to minimize noise coupling. Supply requirements are fully specified in Table 1 (DC Specifications) and "Power Supply Recommendations" (Page 134).
