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

SY87724L

is

manufactured

in

Micrel’s

high

performance ASSET2™ silicon bipolar process.

Micrel provides a complete protocol transparent solution

the SY87724L integrated MUX/DEMUX.
