Sc1004 – Gigabit MAC GMII/PMA
High
performance, rich in functions, small area MAC controller with
GMII I/F or PMA I/F with internal 8b/10b encoder/decoder and
Auto-Negotiation full capabilities.
It
has an Easy To Use Application Interface (Simple MAC I/F) suitable
for all applications including L2/L3 intensive hardware switching,
Network Processor Applications and also NIC card Applications.
- IEEE 802.3,2000 Edition
compliant.
- Full Duplex operation.
- GMII for an external PHY
or PMA interface with internal 8b/10b Encoder/Decoder.
- 8KB receive FIFO (size adjustable)
- 256 Bytes transmit FIFO
(size of transmit FIFO can be increased).
- IEEE 802.3,2000 full compliant
Auto-Negotiation (with Next Page implementation).
- Flow Control from the FIFO
level or from the System Interface.
- Optional 4 exact address
registers and multicast support.
- Capable of promiscuous mode
operation for test, switching or special applications.
- Option of stripping CRC
at receive and Per packet inserting CRC at transmission.
- Programmable options allow
selective reception of MAC control types, oversized, jumbo
and erroneous packets.
- Auto insert Flow-Control
packet based on programmable watermark levels or external
pins (System or Queues Levels).
- Programmable threshold level
to start transmitting the packet.
- Programmable Inter-Frame
Gap (IFG) and Flow Control value.
- Full transmit/receive statistics.
- 16/32b user registers access
interface.
- Extensive management counters
for RMON support.
- Provides external loopback
option.
- Management GigaMac MDIO
master interface to an external PHY (just for GMII mode).
- Padding option for less
then minimum size packets.
- If programmed it will automatically
generate and test the standard test patterns.
- Support Jumbo (9K) packet
option
- All outputs registered.
- L3, VLAN support.
- 33MHz to 66MHz (or higher)
Host Clock operation for generic CPU interface.
- 125MHz or higher system
clock - tested from 66MHz to 200MHz.
