ADC3xxx, ADC3xJxx EVM User’s Guide
This document is intended to serve as a user’s guide for the ADC3xxx EVM and ADC3xJxx EVM. The
EVMs provide a platform for evaluating the ADC3xxx which is a dual- or quad-channel, 12- or 14-bit serial
LVDS interface, analog-to-digital converter (ADC) with sampling speed grades of 25, 50, 80, and 125
Msps. The ADC3xJxx is a dual- or quad-channel, 12- or 14-bit JESD204B-compliant interface ADC with
sampling speed grades of 50, 80, 125, and 160 Msps. This family of converters only requires a single 1.8-
V supply, provides flexible input clock dividers, and provides internal features for improved 1/f (ADC32xx,
ADC34xx) and SFDR performance. Throughout this document, the abbreviations EVM and ADC3xxxx,
and the term evaluation module are synonymous with the ADC3xxx EVM and ADC3xJxx EVM, unless
otherwise noted.
