LXT9763
Fast Ethernet 10/100 Hex Transceiver with Full MII
Datasheet
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.
A fully independent Media Independent Interface (MII) for each port provides maximum
control for switch and multi-port adapter applications.
In addition to an expanded set of MDIO registers, the LXT9763 provides three discrete LED
driver outputs for each port. The LXT9763 requires only a single 3.3V power supply.
Applications
s 100BASE-T, 10/100-TX, or 100BASE-FX
Switches and multi-port NICs.
Product Features
s Six independent IEEE 802.3-compliant
10BASE-T or 100BASE-TX ports with
integrated filters.
s Proprietary Optimal Signal Processing™
(OSP™) architecture improves SNR by 3
dB over ideal analog filters.
s Baseline wander correction for improved
100BASE-TX performance.
s 100BASE-FX fiber-optic capability on all
ports.
s Supports both auto-negotiation and legacy
systems without auto-negotiation
capability.
s JTAG boundary scan.
s Six MII ports for independent PHY port
operation.
s Configurable via MDIO port or external
control pins.
s Maskable interrupts.
s Very low power 3.3V operation
(380 mW per channel, typical).
s 208-pin PQFP (0-70 ^oC ambient
temperature range).
