General Description
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
performance ASSET2™ silicon bipolar process.
Micrel provides a complete protocol transparent solution
with the AnyRate
the SY87724L integrated MUX/DEMUX.
Datasheets and support documentation can be found on
Micrel’s web site at www.micrel.com.
