CXA3256R

8-bit 120MSPS Flash A/D Converter

Description

The CXA3256R is an 8-bit high-speed flash A/D

converter capable of digitizing analog signals at the

maximum rate of 120MSPS. ECL, PECL or TTL can

be selected as the digital input level in accordance

with the application. The TTL digital output level

allows 1: 2 demultiplexed output.

The CXA3256R is easier to be used by adding the

new functions to the CXA3246Q and adopting a

ultra-small package.
