STMicroelectronics 

STE100P

2.2 Physical Layer

n Integrates the whole Physical layer functions of 100BASE-TX and 10BASE-T

n Provides Full-duplex operation on both 100Mbps and 10Mbps modes

n Provides Auto-negotiation(NWAY) function of full/half duplex operation for both 10 and 100 Mbps

n Provides MLT-3 transceiver with DC restoration for Base-line wander compensation

n Provides transmit wave-shaper, receive filters, and adaptive equalizer

n Provides loop-back modes for diagnostic

n Builds in Stream Cipher Scrambler/ De-scrambler and 4B/5B encoder/decoder

n Supports external transmit transformer with turn ratio 1:1

n Supports external receive transformer with turn ratio 1:1

2.3 LED Display

n 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 ok)

♦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)

2.4 Miscellaneous
