Dual Gigabit Ethernet Controller
•
FEATURES
• Two port full-duplex Gigabit Ethernet
Controller with an industry standard
POS-PHY Level 3™ system interfac e.
• Provides direct connection to optics.
• Connection to copp er Gig ab it Eth ern et
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 synthe sis.
• Provides eight unicast exact-match
address filters to filter fram es based o n
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 Laye r devices Level 3 (POSPHY Level 3 system interface).
• Line side loopback for system level
diagnostic capability.
• 16 bit generic micr oprocessor in terface
for device initi alization, control, r egister
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 Autonegot iation,
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 b ytes. 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
• Option to support IEEE 802.3-1998
flow control at each Ethernet port.
• 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.
