Applications
This DMUX enables users to process high-speed output data streams from fast ana-
log-to-digital converters down to standard FPGA processor speed.
Description
The AT84CS001 is a monolithic high-speed demultiplexer, used to lower a 10-bit data
stream of up to 2.2 Gsps guaranteed rate by a selectable 4 or 2 ratio (a 1:8 ratio may
be achieved by interleaving two DMUXes).
The DMUX is a companion chip designed to fit perfectly with all of Atmel’s high-speed
ADCs and is capable of tracking the ADC’s output sampling rate over all operating fre-
quency and temperature ranges.
Thanks to its LVDS buffers, this DMUX can easily be interfaced with standard high-
speed FPGAs (100
differentially terminated).
The AT84CS001 has the same footprint as Atmel’s TS81102G0 DMUX, with a very
similar pinout. Minimum re-design efforts are required to use this low-power DMUX.
An application note “Replacing Atmel’s TS81102G0 DMUX with Atmel’s AT84CS001
LVDS DMUX” reference 5413, is available to assist in migrating from the TS81102G0
to the AT84CS001.
