LU6612
FASTCAT Single-FET for 10Base-T/100Base-TX
Data Sheet
July 2000
Description
The LU6612 is a single-channel, single-chip complete
transceiver designed specifically for dual-speed
10Base-T and 100Base-TX repeaters and switches.
LU6612 implements:
I
The 10Base-T transceiver function of IEEE 802.3u.
I
The physical coding sublayer (PCS) of IEEE 802.3u.
I
The physical medium attachment (PMA) of IEEE
802.3u.
I
Autonegotiation of IEEE 802.3u.
I
MII management of IEEE802.3u.
I
Physical medium dependent (PMD) of IEEE802.3u.
This device supports operation over category 3
unshielded twisted-pair (UTP) cable, according to IEEE
802.3u 10Base-T specification, and over category 5,
Type 1, UTP and Type 1 shielded twisted-pair cable,
according to IEEE802.3u 100Base-X specification.
Figure 1 illustrates a functional overview of the LU6612
while Figure 2 details the functions. Figure 3 shows
how the LU6612 interfaces to the twisted pair.
