Product Descriptions

The CS8952 uses CMOS technology to deliver a high-performance, low-cost 100BASE-X/10BASE-T PhysicalLayer (PHY) line interface. It makes use of an adaptiveequalizer optimized for noise and near end crosstalk(NEXT) immunity to extend receiver operation to cablelengths exceeding 160 m. In addition, the transmit cir-cuitry has been designed to provide extremely lowtransmit jitter (<400 ps) for improved link partner perfor-mance. Transmit driver common mode noise has beenminimized to reduce EMI for simplified FCC certification.

The CS8952 incorporates a standard Media Indepen-dent Interface (MIl) for easy connection to a variety of 10and 100 Mb/s Media Access Controllers (MACs). TheCS8952 also includes a pseudo-ECL interface for usewith 100Base-FX fiber interconnect modules.
