AN983B Datasheet, PDF (12/91 Pages) List of Unclassifed Manufacturers – PCI/miniPCI-to-Ethernet LAN Controller

AN983B PCI/miPCI Fast Ethernet Controller with integrated PHY
Provides serial interface for read/write 93C46/66 EEPROM
Automatically loads device ID, vendor ID, subsystem ID, subsystem vendor ID,
Maximum-Latency, and Minimum-Grand from the 64 byte contents of 93C46/66 after
PCI reset de-asserted in PCI environment.
MAC/PHYSICAL
Integrates the whole Physical layer functions of 100BASE-TX and 10BASE-T
Provides Full -duplex operation on both 100Mbps and 10Mbps modes
Provides Auto-negotiation (NWAY) function of full/half duplex operation for both 10 and
100 Mbps
Provides transmit wave-shaper, receive filters, and adaptive equalizer
Provides MLT-3 transceiver with DC restoration for Base-line wander compensation
Provides MAC and Transceiver (TXCVR) loop-back modes for diagnostic
Builds in Stream Cipher Scrambler/ De-scrambler and 4B/5B encoder/decoder
Supports external transmit transformer with turn ratio 1:1
Supports external receive transformer with turn ratio 1:1
