78Q2123/78Q2133 MicroPHY™  
10/100BASE-TX Transceiver  
DATA SHEET  
April 2009  
FEATURES  
DESCRIPTION  
The 78Q2123 and 78Q2133, MicroPHYTM, 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.
