LXT9761/9781

Fast Ethernet 10/100 Multi-Port Transceiver with RMII

Datasheet

The LXT9781 is an eight-port PHY Fast Ethernet Transceiver that supports IEEE 802.3 physical

layer applications at both 10 Mbps and 100 Mbps. It provides a Reduced Media Independent

Interface (RMII) for switching and other independent port applications. The LXT9761 offers the

same features and functionality in a six-port device. This data sheet uses the singular designation

“LXT97x1” to refer to both devices.

All network ports provide a combination twisted-pair (TP) or pseudo-ECL (PECL) interface for

a 10/100BASE-TX or 100BASE-FX connection.

The LXT97x1 provides three discrete LED driver outputs for each port, as well as eight global

serial LED outputs. The device supports both half- and full-duplex operation at 10 Mbps and 100

Mbps, and requires only a single 3.3V power supply.

Applications

■ 100BASE-T, 10/100-TX, or 100BASE-FX

Switches and multi-port NICs.

Product Features

■ Six or eight IEEE 802.3-compliant

10BASE-T or 100BASE-TX ports with

integrated filters

■ Supports both auto-negotiation and legacy

systems without auto-negotiation capability

■ JTAG boundary scan

■ 3.3V operation

■ Multiple Reduced MII (RMII) ports for

■ Optimized for dual-high stacked R45

independent PHY port operation

applications

■ Configurable via MDIO port or external

■ Proprietary Optimal Signal Processing™

architecture improves SNR by 3 dB over

ideal analog filters

■ Robust baseline wander correction

100BASE-FX fiber-optic capability on all

ports

control pins.

■ Maskable interrupts

■ Low power consumption (390 mW per

port, typical)

■ 208-pin PQFP (LXT9761 and LXT9781)

■ 272-pin PBGA (LXT9781 only)
