Description
The CS61880 is a full-featured Octal E1 short-haul LIU
that supports 2.048 Mbps data transmission for both E1
75
and E1 120
applications. Each channel provides
crystal-less jitter attenuation that complies with the most
stringent standards. Each channel also provides internal
AMI/HDB3 encoding/decoding. To support enhanced
system diagnostics, channel zero can be configured for
G.772 non-intrusive monitoring of any of the other 7
channels’ receive or transmit paths.
The CS61880 makes use of ultra low power matched im-
pedance transmitters and receivers to reduce power
beyond that achieved by traditional driver designs. By
achieving a more precise line match, this technique also
provides superior return loss characteristics. Additional-
ly, the internal line matching circuitry reduces the
external component count. All transmitters have controls
for independent power down and High-Z.
Each receiver provides reliable data recovery with over
12 dB of cable attenuation. The receiver also incorpo-
rates LOS detection compliant to the most recent
specifications.
