Overview
July 1997 PRELIMINARY ML6697 100BASE-TX Physical Layer with MII GENERAL DESCRIPTION The ML6697 implements the complete physical layer of the Fast Ethernet 100BASE-TX standard.
The ML6697 offers a single-chip per-port solution for MII-based repeater applications.
The ML6697 interfaces to the controller through the Media Independent Interface (MII).
The ML6697 functionality includes 4B/5B encoding/ decoding, Stream Cipher scrambling/descrambling, 125MHz clock recovery/generation, receive adaptive equalization, baseline wander correction, and MLT-3 transmitter.
FEATURES n Single-chip 100BASE-TX physical layer n Compliant to IEEE 802.
3u 100BASE-TX standard n Supports MII-based repeater applications n Compliant MII (Media Indendent Interface) n 4B/5B encoder/decoder n Stream Cipher scrambler/descrambler n 125MHz clock recovery/generation n Baseline wander correction n Adaptive equalization and MLT-3 encoding/decoding BLOCK DIAGRAM (PLCC Package) 1 9 TXCLKIN TXCLK CLOCK SYNTHESIZER 3 4 5 6 7 8 TXD3 TXD2 TXD1 TXD0 TXEN TXER CRS RXEN RXCLK RXD3 RXD2 RXD1 RXD0 RXDV RXER PCS TRANSMIT STATE MACHINE 4B/5B ENCODER SCRAMBLER NRZ TO NRZI ENCODER SERIALIZER MLT-3 ENCODER FLP/100BASE-TX TWISTED PAIR DRIVER TPOUTP TPOUTN RTSET 40 39 37 18 19 17 10 12 14 16 21 23 CLOCK AND DATA RECOVERY NRZI TO NRZ DECODER PCS RECEIVE STATE MACHINE 5B/4B DECODER DESCRAMBLER MII MANAGEMENT REGISTERS AND CONTROL LOGIC DESERIALIZER EQUALIZER BLW CORRECTION MLT-3 DECODER LOOPBACK MUX TPINP TPINN CMREF RGMSET LINK100 45 44 46 36 43 PHYAD0 PHYAD1 PHYAD2 PHYAD3 32 24 25 29 30 31 PHYAD4 33 MDIO MDC 1 ML6697 PIN CONFIGURATION ML6697 52-Pin PLCC (Q52) TXCLKIN AGND1 AVCC1 TXD0 TXD1 TXD2 TXD3 TXEN NC NC NC NC 7 TXER TXCLK RXD3 DGND1 RXD2 DVCC1 RXD1 DGND2 RXD0 RXCLK CRS RXEN DGND3 8 9 10 11 12 13 14 15 16 17 18 19 20 21 RXDV 6 5 4 3 2 1 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 CMREF TPINP TPINN LINK100 AVCC2 AGND2 TPOUTP TPOUTN AGND3 RTSET RGMS...
