Features
- Two port full-duplex Gigabit Ethernet Controller with an industry standard POS-PHY Level 3 system interface.
- Provides direct connection to optics.
- 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.
- Supports dual IEEE 802.3 -1998 GMII/TBI interfaces for connection to copper Gigabit Ethernet physical layer devices.
- Provides dual standard IEEE 802.3 Gigabit Ethernet MACs for frame verification.
- Provides on-chip data recovery and clock synthesis.
|
- Provides eight unicast exact-match address filters to filter frames based on DA, SA, or VID.
- Each address filter can indicate whether to accept or discard based on a match.
- Provides 64-group multicast address filter.
- Internal 16 kbyte TX and 64 kbyte RX FIFOs to accommodate system latencies.
- SATURN® compatible interface for Packet-Over-SONET Physical Layer and Link Layer devices Level 3 (POS-PHY Level 3 system interface).
- Line side loopback for system level diagnostic capability.
- 16 bit generic microprocessor interface for device initialization, control, register and per port statistics access.
|
GIGABIT ETHERNET MAC
- Verifies frame integrity (FCS and length checks).
- Errored frames can be filtered or passed to a higher layer device.
- Automatic Base Page Autonegotiation, extended Autonegotiation (Next Page) supported via host.
- Egress Ethernet frame encapsulation (pad to minimum size, add preamble, IFG and CRC generation).
- Supports Ethernet 2.0, IEEE 802.3 LLC and IEEE 802.3 SNAP/LLC encoding formats, and VLAN tagged frames.
|
- Minimum frame size 64 bytes. Supports jumbo frames up to 9.6 kbytes.
- Supports big endian data formats.
- Programmable inter-packet gap (IPG).
- Loopback for diagnostic capability through GMAC.
|
FLOW CONTROL

- Programmable watermarks for full/empty FIFO conditions.
- Automatic generation of pause frames based on FIFO fill levels.
|
- Upper layer device can flow control Ethernet ports using side-band or host signaling to cause generation of a Pause frame.
- Provides per-port side-band Pause state indication for upstream devices.
- Loss-less flow control on all valid frames up to 9.6 kbytes.
|
STATISTICS
- 40 bit counters are used to ensure rollover compliance with IEEE 802.3-1998.
