Analog Devices Inc. AD9652BBCZ-310

Overview

AD9652BBCZ-310 from Analog Devices is a dual, 16-bit, 310 MSPS analog-to-digital converter (ADC) designed for high-speed signal acquisition in wideband RF and IF sampling systems. It operates from 3.3 V and 1.8 V supplies, delivers 75.0 dBFS SNR at 70 MHz, supports up to 465 MHz full-power bandwidth, and outputs interleaved DDR LVDS data with multichip SYNC capability - used in military radar receivers and multimode digital baseband processing.

For engineers reviewing the AD9652BBCZ-310 datasheet, AD9652BBCZ-310 pinout, AD9652BBCZ-310 application, or AD9652BBCZ-310 equivalent, key selection criteria include its dual-channel 16-bit resolution at 310 MSPS, −157.6 dBFS/Hz noise spectral density, 90 dB channel isolation, on-chip duty cycle stabilizer, and support for 1.24 GHz clock input with integer division (1–8).

Technical Context

The AD9652BBCZ-310 implements two independent pipelined ADC cores with integrated error correction logic, enabling accurate interleaving of 16-bit output data onto a single DDR LVDS port. Its proprietary differential analog input maintains SNR >73 dBFS up to 170 MHz while supporting programmable input span (2–2.5 V_p-p) and on-chip 3.3 V buffer to simplify driver interface.

It features a fully synchronous SPI interface (3-wire, 1.8 V/3.3 V compatible), internal voltage reference (1.25 V default), and configurable power-down/standby modes. The SYNC input enables deterministic multichip timing alignment, critical for phased-array radar and MIMO receiver calibration.

Key Specifications

Pinout & Package

FAQ

What is the maximum input clock frequency supported by the AD9652BBCZ-310?

The AD9652BBCZ-310 accepts differential clock inputs up to 1.24 GHz. It incorporates an integer clock divider (1, 2, 4, or 8) to generate the internal sample clock, allowing flexible clock source selection while maintaining precise timing control. The duty cycle stabilizer ensures robust operation even with asymmetric input clocks.

Does the AD9652BBCZ-310 include an on-chip voltage reference?

Yes, the AD9652BBCZ-310 integrates a precision 1.25 V voltage reference (default), accessible via the VREF pin. It also supports external reference operation through the same pin, with SENSE pin configuration determining reference mode. This eliminates the need for external reference ICs in most applications.

How does the AD9652BBCZ-310 handle overrange conditions?

The AD9652BBCZ-310 provides dedicated LVDS overrange outputs (OR+/OR−) that assert when either channel's input exceeds full-scale range. These flags operate independently per channel and are synchronized to the DCO± clock, enabling real-time saturation detection without reading status registers.

What is the pipeline latency of the AD9652BBCZ-310, and is it deterministic?

The AD9652BBCZ-310 has a fixed pipeline latency of 26 clock cycles, which is fully deterministic and repeatable. This value remains constant across temperature, supply, and input conditions, enabling precise timing alignment in multichip configurations using the SYNC input.

Can the AD9652BBCZ-310 operate with only 1.8 V supplies?

No - the AD9652BBCZ-310 requires both 3.3 V (AVDD3) and 1.8 V (AVDD, AVDD_CLK, DRVDD, SPIVDD) supplies. The 3.3 V rail powers the on-chip analog input buffer and reference circuitry; omitting it will prevent proper analog front-end operation and degrade SNR/SFDR performance.
