DESCRIPTION
The 78Q2120C is a 10BASE-T/100BASE-TX Fast
Ethernet transceiver. It includes integrated MII,
ENDECs, scrambler/descrambler, dual-speed clock
recovery, and full-featured auto-negotiation function.
The transmitter includes an on-chip pulse-shaper and
a low-power line driver. The receiver has an adaptive
equalizer and a baseline restoration circuit required
for accurate clock and data recovery. The transceiver
interfaces to Category-5 unshielded twisted pair (Cat-
5 UTP) cabling for 100BASE-TX/10BASE-T and
Category-3 unshielded twisted pair for 10BASE-T.
Connection to the line media is via 1:1 isolation
transformers. No external filter is required. Interface
to the MAC is accomplished through an IEEE-802.3
compliant Media Independent Interface (MII). The
product is fabricated in an advanced CMOS process
for high performance and low power operation.
