The SY87724L is a complete serial data multiplexer and
demultiplexer, capable of operating at up to 2.7GHz. The
device provides for muxing and demuxing to 4, 5, 8, or 10
bit wide buses.
The SY87724L can accept a synchronous code group or
octet boundary input, and uses this input for parallel data
alignment.
The SY87724L is manufactured in Micrel’s high
performance ASSET2™ silicon bipolar process.
Micrel provides a complete protocol transparent solution
with the AnyRate^® SY87721L CDR/CMU SY87729L, and
the SY87724L integrated MUX/DEMUX.
