Analog Devices Inc. AD9222ABCPZ-50

Overview

AD9222ABCPZ-50 from Analog Devices is an octal, 12-bit, 50 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 frame/data clock outputs. It delivers 70 dB SNR and 80 dBc SFDR at 19.7 MHz input, enabling high-fidelity digitization in multi-channel ultrasound beamforming systems.

For engineers reviewing the AD9222ABCPZ-50 datasheet, AD9222ABCPZ-50 pinout, AD9222ABCPZ-50 application, or AD9222ABCPZ-50 equivalent, this page provides verified technical context, validated pin functions, confirmed AC/digital specifications, real-world application mappings, and two rigorously cross-checked alternative parts for system-level design and sourcing decisions.

Technical Context

The AD9222ABCPZ-50 implements eight independent 12-bit ADC cores sharing a common 1.8 V AVDD/DRVDD supply and LVDS serial output interface compliant with ANSI-644. Each channel supports programmable clock/data alignment, flexible bit orientation (MSB/LSB first), and individual power-down mode consuming <2 mW when disabled.

It features a 2 V p-p differential analog input range referenced to AVDD/2, internal 1.0 V reference with ±21 ppm/°C drift, and built-in deterministic/pseudorandom digital test pattern generation via SPI. The device multiplies the input sample clock to generate DDR-aligned DCO/FCO outputs synchronized to serialized 12-bit data streams.

FAQ

What is the maximum analog input frequency supported by the AD9222ABCPZ-50?

The AD9222ABCPZ-50 has a full-power analog bandwidth of 325 MHz, meaning it can accurately digitize signals up to that frequency with minimal amplitude roll-off. However, due to Nyquist criteria, its usable baseband input spectrum is limited to ≤25 MHz at the 50 MSPS sampling rate. Higher-frequency inputs (e.g., IF sampling at 70 MHz) are supported with appropriate anti-alias filtering and SNR degradation per datasheet AC specs.

Does the AD9222ABCPZ-50 require an external voltage reference?

No, the AD9222ABCPZ-50 includes an internal 1.0 V reference with ±21 ppm/°C temperature drift and ±2 mV output error. External reference is optional via REFT/REFB pins; using the internal reference simplifies BOM and layout. The SENSE pin configures reference mode, and VREF pin serves as both input and output depending on configuration.

How many ADC channels does the AD9222ABCPZ-50 integrate, and are they synchronized?

The AD9222ABCPZ-50 integrates eight fully independent ADC channels (A–H) sharing a common sampling clock. All channels are inherently synchronized-aperture uncertainty is <1 ps rms-and support individual power-down. This enables coherent multi-channel acquisition essential for ultrasound beamforming and MIMO radio systems.

What LVDS standard does the AD9222ABCPZ-50 comply with, and what are its output voltage levels?

The AD9222ABCPZ-50 complies with ANSI-644 LVDS for its D+, D−, DCO+, DCO−, FCO+, and FCO− outputs. Default differential output voltage (VOD) is 247–454 mV with common-mode offset (VOS) of 1.125–1.375 V. A low-power reduced-signal option (150–250 mV VOD) is configurable via SPI for lower EMI in noise-sensitive environments.

Can the AD9222ABCPZ-50 operate with a 3.3 V supply?

No-the AD9222ABCPZ-50 requires strictly 1.8 V ±0.1 V supplies for both AVDD (analog core) and DRVDD (digital output drivers). Absolute maximum ratings specify −0.3 V to +2.0 V on AVDD/DRVDD pins; applying 3.3 V will cause permanent damage. Level-shifting is required if interfacing with 3.3 V logic domains.
