DUAL GIGABIT ETHERNET CONTROLLER
2 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.
