Applications
This DMUX enables users to process high-speed output data streams from fast analog-to-digital converters down to stan-
dard 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 might be achieved by interleaving two DMUXes).
The DMUX is a companion chip designed to fit perfectly with all of e2v’s high-speed ADCs and is capable of tracking the
ADC’s output sampling rate over all operating frequency and temperature ranges.
Thanks to its LVDS buffers, this DMUX can easily be interfaced with standard high-speed FPGAs (100Ω differentially
terminated).
The AT84CS001 has the same footprint as e2v’s TS81102G0 DMUX, with a very similar pinout. Minimum re-design efforts
are required to use this low-power DMUX. An application note Migration from AT84AS008 to EV10AS008B reference 0810,
is available to assist in migrating from the TS81102G0 to the AT84CS001.
