2.2.2 PCI Express Interface
The PCI Express (launched in 2002) interface is a new serial I/O
interface standard being used in next generation computer, storage and
communications platforms. This scalable interface allows vendors to
choose the number of 2.5 gigabit serial lanes (two to 16) most suitable
to their product design and application need.
The PCI Express interface featured on the LSI7404EP-LC includes:
•
8 serial I/O lanes, 2.5 GHz, full duplex
•
Fully PCI-compatible software model
•
Serial EEPROM configuration storage
2.2.3 FC Interface
The LSIFC949X processor provides the FC functionality for all the
LSI Logic 4 Gbit/s FC host adapters. The LSIFC949X processor
generates signal timing and link protocol in compliance with FC
standards.
The FC interface includes these features:
•
4 Gbit/s serial link (backward compatible with 1 Gbit/s and 2 Gbit/s)
•
LSIFC949X processor functionality:
– Class 3, Arbitrated Loop (AL), Fabric, Point-to-Point
– 2 Kbyte frame payloads
– Multiframe transmit and receive buffering
•
Link activity/link fault LED
