This document describes the features and characteristics of the Quad, 12-Bit, 40/65 MSPS Serial LVDS 1.8 V A/D Converter AD9228.
The AD9228 is a quad, 12‑bit ADC that operates at up to 65 MSPS and delivers 119 mW per channel at full speed. It features LVDS serial output, programmable clock and data alignment, and built‑in digital test pattern generation, all powered from a single 1.8 V supply.
Designed for medical imaging, ultrasound, quadrature radio receivers, optical networking and test equipment, the device is offered in a RoHS‑compliant 48‑lead LFCSP and operates over an industrial temperature range of –40 °C to +85 °C.

The AD9228 can operate at up to 65 MSPS.
It requires a single 1.8 V supply for both AVDD and DRVDD.
The device provides a default LVDS (ANSI‑644) serial output.
Each channel consumes about 119 mW when running at 65 MSPS.
