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.
