STE100P
2.2 Physical Layer
■ 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 1:1
■ Supports external receive transformer with turn ratio 1:1
2.3 LED Display
The LED display, consists of five LEDs having the following characteristics:
■ 10 Mbps Speed LED: 10Mbps(on) or 100Mbps(off)
■ 100 Mbps Speed LED: 100Mbps(on) or 10Mbps(off)
■ TX/RX Activity LED: Blinks at 10Hz when receiving, but not colliding
■ Link LED: On when a good link is detected, blinks when there is TX or RX activity
■ Full Duplex / Collision LED: On during Full Duplex operation. Blinks at 20Hz to indicate a collision
2.4 Miscellaneous
■ Standard 64-pin QFP package pinout
