DESCRIPTION
The 78Q2123 and 78Q2133, MicroPHY
TM, are the
smallest 10BASE-T/100BASE-TX Fast Ethernet
transceivers in the market. They include integrated
MII, ENDECs, scrambler/descrambler, dual-speed
clock recovery, and full-featured auto-negotiation
functions. 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
applications, and Category-3 unshielded twisted pair
(Cat-3 UTP) for 10BASE-T applications. The MDI is
connected to the line media via dual 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
78Q2123/78Q2133 are intended to serve the
embedded Ethernet market, tailored specifically to the
needs of game consoles, broadband modems,
printers, set top boxes and audio/visual equipment. It
is designed for low-power consumption and operates
from a single 3.3V supply. The 78Q2123 is rated for
commercial temperature range and the 78Q2133 is
rated for industrial temperature range.
