Product Descriptions
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 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. 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.
