STE100P 데이터시트 - STMicroelectronics

DESCRIPTION
The STE100P, also referred to as STEPHY1, is a high performance Fast Ethernet physical layer interface for 10Base-T and 100Base-TX applications.
It was designed with advanced CMOS technology to provide a Media Independent Interface (MII) for easy attachment to 10/100 Media Access Controllers (MAC) and a physical media interface for 100Base-TX of IEEE802.3u and 10Base-T of IEEE802.3.

FEATURES
Industry standard
■ IEEE802.3u 100Base-TX and IEEE802.3 10Base-T compliant
■ Support for IEEE802.3x flow control
■ IEEE802.3u Auto-Negotiation support for 10Base-T and 100Base-TX
■ MII interface
■ Standard CSMA/CD or full duplex operation supported
■ Industrial temperature compliant

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

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

Miscellaneous
■ Standard 64-pin QFP package pinout
