Fast Ethernet 10/100 Hex Transceiver with Full MII

The LXT9763 is a six-port PHY Fast Ethernet Transceiver that supports IEEE 802.3 physical layer applications at both 10 and 100 Mbps. The mixed-signal adaptive equalization and clock recovery with proprietary Optimal Signal Processing (OSP?) architecture improves SNR 3 dB over ideal analog filters. All six network ports provide a combination twisted-pair (TP) or pseudo-ECL (PECL) interface for a 10/100BASE-TX or 100BASE-FX connection. The LXT9763 supports both half- and full-duplex operation at 10 and 100 Mbps.

Product Features

■ Six independent IEEE 802.3-compliant 10BASE-T or 100BASE-TX ports with integrated filters.

■ Proprietary Optimal Signal Processing? (OSP?) architecture improves SNR by 3 dB over ideal analog filters.

■ Baseline wander correction for improved 100BASE-TX performance.

■ 100BASE-FX fiber-optic capability on all ports.

■ Supports both auto-negotiation and legacy systems without auto-negotiation capability.

■ JTAG boundary scan.

■ Six MII ports for independent PHY port operation.

■ Configurable via MDIO port or external control pins.

■ Maskable interrupts.

■ Very low power 3.3V operation (380 mW per channel, typical).

■ 208-pin PQFP (0-70 oC ambient temperature range).

Applications

■ 100BASE-T, 10/100-TX, or 100BASE-FX Switches and multi-port NICs.
