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:
The 10Base-T transceiver function of IEEE 802.3u.
The physical coding sublayer (PCS) of IEEE 802.3u.
The physical medium attachment (PMA) of IEEE 802.3u.
Autonegotiation of IEEE 802.3u.
MII management of IEEE 802.3u.
Physical medium dependent (PMD) of IEEE 802.3u.
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 IEEE 802.3u 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.
