• 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 MLT-3 transceiver with DC restoration for Base-line wander compensation
• Provides transmit wave-shaper, receive filters, and adaptive equalizer
• Provides loop-back modes for diagnostic
• Builds in Stream Cipher Scrambler/ De-scrambler and 4B/5B encoder/decoder
• Supports external transmit transformer with turn ratio 1.41:1
• Supports external receive transformer with turn ratio 1:1
• Provides 2 kinds of LED display mode:
• First mode - 3 LED displays for 100Mbps(on) or 10Mbps(off)
• Link(Keeps on when link ok) or Activity(Blink with 10Hz when receiving or transmitting but not collision)
• FD(Keeps on when in Full duplex mode) or Collision(Blink with 20Hz when colliding)
• Second mode – 4 LED displays for 100 Link(On when 100M link or 10 Link(On when 10M link ok
• Activity (Blink with 10Hz when receiving or transmitting)
• FD(Keeps on when in Full duplex mode) or Collision(Blink with 20Hz when colliding)
