Cirrus Logic CS8952-CQ

ТрансиверIEEE 802.3

Overview

The CS8952-CQ uses CMOS technology to deliver a high-performance, 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 meters. In addition, the transmit circuitry has been designed to provide extremely low transmit jitter (<400 ps) for improved link partner performance. Transmit driver common mode noise has been minimized to reduce EMI (electromagnetic interference) for simplified FCC certification. The CS8952-CQ incorporates a standard media independent interface (MII) for easy connection to a variety of 10 Mbps and 100 Mbps media access controllers (MACs). The CS8952-CQ also includes a pseudo-ECL (emitter coupled logic) interface for use with 100Base-Fx fiber interconnect modules.
