LXT9762/9782
Fast Ethernet 10/100 Multi-Port Transceiver with Serial MII
Datasheet
General Description
The LXT9782 is an eight-port PHY Fast Ethernet Transceiver that supports IEEE 802.3 physical
layer applications at both 10 and 100 Mbps. The LXT9762 offers the same features and
functionality in a six-port device. This data sheet uses the singular designation “LXT97x2” to
refer to both devices.
The LXT97x2 interfaces multiple Serial Media Independent Interface (SMII) compliant
controllers to 10BASE-T and/or 100BASE-TX media.
All network ports provide a combination twisted-pair (TP) or pseudo-ECL (PECL) interface for
a 10/100BASE-TX or 100BASE-FX connection.
The LXT97x2 provides three discrete LED drivers for each port, and eight global serial LED
outputs. It supports both half- and full-duplex operation at 10 and 100 Mbps and requires only a
single 3.3V power supply.
Application
a73 100BASE-T, 10/100-TX, or 100BASE-FX Switches and multi-port NICs.
Product Features
a73 Multiple independent IEEE 802.3-
compliant 10/100 ports with integrated
filters
a73 Proprietary Optimal Signal Processing
(OSP?) design improves SNR by 3 dB
over ideal analog filters
a73 Robust baseline wander correction for
improved 100BASE-TX performance
a73 100BASE-FX fiber-optic capability on all
ports
a73 Supports both auto-negotiation and legacy
systems without auto-negotiation capability
a73 JTAG boundary scan
a73 Multiple Serial MII (SMII) ports for
independent PHY port operation
a73 Configurable via MDIO port or external
control pins
a73 Maskable interrupts
a73 Very low power consumption
(400 mW per port, typical)
a73 3.3V operation
a73 208-pin PQFP and 272-lead BGA
a73 0-70
