Description
The CS8952 uses CMOS technology to deliver a high-
performance, low-cost 100BASE-X/10BASE-T Physical
Layer (PHY) line interface. It makes use of an adaptive
equalizer optimized for noise and near end crosstalk
(NEXT) immunity to extend receiver operation to cable
lengths exceeding 160 m. In addition, the transmit cir-
cuitry has been designed to provide extremely low
transmit jitter (<400 ps) for improved link partner perfor-
mance. Transmit driver common mode noise has been
minimized to reduce EMI for simplified FCC certification.
The CS8952 incorporates a standard Media Indepen-
dent Interface (MII) for easy connection to a variety of 10
and 100 Mb/s Media Access Controllers (MACs). The
CS8952 also includes a pseudo-ECL interface for use
with 100Base-FX fiber interconnect modules.
