78Q2123/78Q2133 MicroPHYâ„¢ 10/100BASE-TX Transceiver Simplifying System IntegrationTM DATA SHEET April 2010 DESCRIPTION The 78Q2123 and 78Q2133, MicroPHY , 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 pulseshaper 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.
