LU6612 FASTCAT ^TM Single-FET
for 10Base-T/100Base-TX
Features
General
10 Mbits/s Transceiver
s Compatible with IEEE * 802.3u 10Base-T standard
for twisted-pair cable
s Autopolarity detection and correction
s Adjustable squelch level for extended wire line
length capability (2 levels)
s Interfaces with IEEE 802.3u media independent
interface (MII)
s On-chip filtering eliminates the need for external fil-
ters
s Half- and full-duplex operations
100 Mbits/s Transceiver
s Compatible with IEEE 802.3u MII (clause 22), PCS
(clause 23), PMA (clause 24), autonegotiation
(clause 28), and PMD (clause 25) specifications
s Scrambler/descrambler bypass
s Encoder/decoder bypass
s 3-statable MII in 100 Mbits/s mode
s Selectable carrier sense signal generation (CRS
asserted during either transmission or reception in
half duplex, CRS asserted during reception only in
full duplex)
s Selectable MII or 5-bit code group interface
s Half- or full-duplex operations
s On-chip filtering and adaptive equalization that
eliminates the need for external filters
s Autonegotiation (IEEE 802.3u clause 28):
— Fast link pulse (FLP) burst generator
— Arbitration function
— Accepts preamble suppression
— Operates up to 12.5 MHz
s Supports the station management protocol and
frame format (clause 22):
— Basic and extended registers
— Supports next-page function
— Accepts preamble suppression
— Operates up to 12.5 MHz
s Supports the following management functions via
pins if station management is unavailable:
— Speed select
— Encoder/decoder bypass
— Scrambler/descrambler bypass
— Full duplex
— Autonegotiation
s Supports half- and full-duplex operations
s Provides four status signals: receive/transmit activ-
ity, full duplex, link integrity, and speed indication
s Powerdown mode for 10 Mbits/s and 100 Mbits/s
operation
s Loopback for 10 Mbits/s and 100 Mbits/s operation
s 0.35 µm low-power CMOS technology
s 64-pin TQFP
s Single 5 V power supply
