2.2 FIFO
s
Provides independent transmission and receiving FIFOs, each 2k bytes long
s
Pre-fetches up to two transmit packets to minimize inter frame gap (IFG) to 0.96us
s
Retransmits collided packet without reload from host memory within 64 bytes.
s
Automatically retransmits FIFO under-run packet with max. drain threshold until 3rd time retry failure
threshold of next packet.
2.3 PCI I/F
s
Provides 32-bit PCI bus master data transfer
s
Supports PCI clock with frequency from 0Hz to 33MHz
s
Supports network operation with PCI system clock from 20MHz to 33MHz
s
Provides performance meter and PCI bus master latency timer for tuning the threshold to enhance the
performance
s
Provides burst transmit packet interrupt and transmit/receive early interrupt to reduce host CPU
utilization
s
As bus master, supports memory-read, memory-read-line, memory-read-multiple, memory-write,
memory-write-and-invalidate command
s
Supports big or little endian byte ordering
2.4 EEPROM/Boot ROM I/F
s
Provides writeable Flash ROM and EPROM as boot ROM, up to 128kB
s
Provides PCI to access boot ROM by byte, word, or double word
s
Re-writes Flash boot ROM through I/O port by programming register
s
Provides serial interface for read/write 93C46 EEPROM
s
Automatically loads device ID, vendor ID, subsystem ID, subsystem vendor ID, Maximum-Latency, and
Minimum-Grand from the 64 byte contents of 93C46 after PCI reset de-asserted
2.5 MAC/Physical
s
Integrates the complete set of Physical layer 100BASE-TX and 10BASE-T functions
s
Provides Full-duplex operation in both 100Mbps and 10Mbps modes
s
Provides Auto-negotiation (NWAY) function of full/half duplex operation for both 10 and 100 Mbps
s
Provides MLT-3 transceiver with DC restoration for Base-line wander compensation
s
Provides transmit wave-shaper, receive filters, and adaptive equalizer
s
Provides MAC and Transceiver (TXCVR) loop-back modes for diagnostic
s
Built-in Stream Cipher Scrambler/ De-scrambler and 4B/5B encoder/decoder
s
Supports external transmit and receive transformer with 1:1 turn ratio
2.6 LED Display
s
Provides 2 LED display modes:
3 LED displays for
100Mbps (on) or 10Mbps (off)
Link (Remains on when link ok) or Activity (Blinks at 10Hz when receiving or transmitting collision-free)
FD (Remains on when in Full duplex mode) or when collision detected (Blinks at 20Hz)
