FEATURES

2.1

General

• Two port full-duplex Gigabit Ethernet Controller with an industry standard POS-PHY

Level 3 system interface.

• Provides direct connect to optics via two internal Serializer/Deserializer (SERDES)

• Provides connection to copper Gigabit Ethernet physical layer devices via two GMII

interfaces.

• Incorporates dual SERDES, compatible to IEEE 802.3 1998 PMA physical layer

specification.

• Provides on-chip data recovery and clock synthesis.

• Supports dual IEEE 802.3 -1998 GMII interfaces for connection to copper Gigabit

Ethernet physical layer devices.

• Provides dual standard IEEE 802.3 Gigabit Ethernet MACs for frame verification.

• Enables frame filtering on 8 unicast or 64 multicast entries.

• Internal 16k byte egress and 64k byte ingress FIFOs per channel to accommodate

system latencies.

• Incorporates SATURN POS-PHY Level 3 32-bit System Interface clocked up to

104 MHz (32 bit mode only).

• Line side loopback capability for system level diagnostic capability.

• Includes 16 bit generic microprocessor interface for device initialization, control,

register and per port statistics access.

• Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board test

purposes.

• Low power 1.8V CMOS device with 3.3V TTL compatible digital inputs (5V TTL

compatible microprocessor inputs) and 3.3V CMOS/TTL compatible digital outputs

within a 352 pin 27mm by 27mm UBGA package.

• Industrial temperature range (-40°C to +85°C).

2.2

Line Side Interface

• SERDES interface provides 2 differential pairs at 1250 MHz for connection to

electrical optical modules.

• GMII interface provides 8 bit wide TX & RX data interfaces at 125 MHz with control

signals for connection to copper Gigabit Ethernet physical layer devices.

• Allows selection between SERDES and GMII interface on a per channel basis.
