Product details
Overview
AD9222ABCPZ-65 from Analog Devices is an octal, 12-bit, 65 MSPS serial LVDS analog-to-digital converter with on-chip sample-and-hold, 1.8 V supply operation, 325 MHz full-power analog bandwidth, and integrated digital test pattern generation. It delivers 70 dB SNR and 80 dBc SFDR at 65 MSPS for high-channel-density data acquisition in ultrasound beamforming systems.
For engineers reviewing the AD9222ABCPZ-65 datasheet, AD9222ABCPZ-65 pinout, AD9222ABCPZ-65 application, or AD9222ABCPZ-65 equivalent, key selection criteria include serial LVDS output compliance (ANSI-644), per-channel power consumption (114 mW at 65 MSPS), 8-channel synchronization capability, and industrial temperature range (−40°C to +85°C) support.
Technical Context
The AD9222ABCPZ-65 implements eight independent ADC cores sharing a common clock domain, each with programmable clock/data alignment and flexible bit orientation. Its serial LVDS interface operates at up to 390 MHz DDR with dedicated DCO and FCO outputs for deterministic data capture.
It features full-chip and individual-channel power-down modes, built-in deterministic/pseudorandom test patterns, and SPI-controlled configuration of resolution (10/12-bit), output drive strength (standard or low-power LVDS), and reference mode (internal 1.0 V or external).

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9252BCPZ-65 | 14-bit resolution, same 65 MSPS rate, identical 64-lead LFCSP package and pinout | Higher dynamic range required for precision instrumentation or radar; increased power (150 mW/channel) | Select when ENOB >11.3 bits is mandatory and layout reuse is critical |
| AD9226ASTZ-65 | Single-channel, 12-bit, 65 MSPS, 48-lead LQFP; no serial LVDS-parallel CMOS outputs | Lower channel density needed; simpler FPGA interface but higher PCB routing complexity and power (135 mW) | Select for cost-sensitive, lower-channel-count designs where parallel bus timing is manageable |
Compared with AD9222ABCPZ-65, AD9252BCPZ-65 offers higher resolution at the cost of increased power and thermal load, while AD9226ASTZ-65 trades integration and noise immunity for interface simplicity and lower unit cost in non-dense layouts.

FAQ
What is the maximum analog input frequency supported by the AD9222ABCPZ-65?
The AD9222ABCPZ-65 has a full-power analog bandwidth of 325 MHz, meaning it can accurately digitize signals with frequency content up to that point while maintaining specified SNR and SFDR performance. This supports undersampling applications for IF signals up to ~150 MHz when combined with appropriate anti-alias filtering and system-level calibration.
Does the AD9222ABCPZ-65 require an external reference voltage?
No, the AD9222ABCPZ-65 includes an internal 1.0 V reference and operates in 1 V mode by default. The SENSE pin configures reference mode, and VREF/REFB/REFT pins allow optional external differential reference use-but external reference is not required for standard operation.
How many ADC channels does the AD9222ABCPZ-65 integrate, and are they synchronized?
The AD9222ABCPZ-65 integrates eight fully synchronized ADC channels (labeled A–H) sharing a common sampling clock. All channels exhibit matched propagation delay and aperture jitter, enabling coherent multichannel acquisition essential for beamforming and diversity reception.
What LVDS standard does the AD9222ABCPZ-65 comply with for its serial output?
The AD9222ABCPZ-65 serial LVDS outputs comply with ANSI TIA/EIA-644, the industry-standard LVDS specification. It also supports a reduced-swing LVDS mode compliant with IEEE 1596.3 for lower power and EMI, selectable via SPI configuration.
Can the AD9222ABCPZ-65 operate at sampling rates below 65 MSPS?
Yes, the AD9222ABCPZ-65 supports minimum sampling rates down to 10 MSPS. Its clock input accepts variable-frequency LVDS/LVPECL/CMOS clocks, and internal circuitry automatically adapts data rate multiplication and timing alignment across the 10–65 MSPS range without reconfiguration.
