Description
The L84225 is a highly integrated Ethernet Transceiver for twisted pair
and fiber Ethernet applications. The L84225 can be configured for either
100 Mbps (100BaseFX or 100BaseTX) or 10 Mbps (10BaseT) Ethernet
operation.
The L84225 consists of four (4) separate and independent channels.
Each channel consists of: 4B5B/Manchester encoder, scrambler,
transmitter with wave shaping and on-chip filters, transmit output driver,
receiver with adaptive equalizer, filters, baseline wander correction, clock
and data recovery, descrambler, 4B5B/Manchester decoder, and
controller interface (MII or RMII).
The addition of internal output waveshaping circuitry and on-chip filters
eliminates the need for external filters normally required in 100BaseTX
and 10BaseT applications.
The L84225 can automatically configure itself for 100 or 10 Mbps and
Full or Half Duplex operation, for each channel independently, using the
on-chip AutoNegotiation algorithm.
The L84225 can access eleven 16-bit registers for each channel through
the Management Interface (MI) serial port. These registers comply with
Clause 22 of IEEE 802.3u and contain configuration inputs, status
outputs, and device capabilities.
The L84225 is ideal as a media interface for 100BaseTX/
100BaseFX/10BaseT switching hubs, repeaters, routers, bridges, and
other multi port applications.
The L84225 is implemented in a low power CMOS technology and
operates with a 3.3V power supply.
