DESCRIPTION:
The IDT77904 and IDT77905 are designed to provide
stable reference platforms for evaluation, design, and produc-
tion of a 155Mbps NIC. The IDT77904 provides a fiber media
physical (PHY) interface; the 77905 supports Unshielded
Twisted Pair, Category 5 (UTP-5) cabling. Otherwise identi-
cal, they both feature complete PCI-bus ATM NIC functional-
ity, plugging directly into PCI bus expansion slots.
COMPATIBILITY AND CONFIGURATION
The board is designed for use in PCI systems, which may
include PC compatibles, MIPS, Alpha, Windows NT systems,
future PowerPC Macintosh systems, and so on. It supports
the 32 bit, 33 MHz, 5V part of the PCI spec, although this also
permits operation in a 64-bit, 33 MHz, 5V PCI slot.
OVERVIEW
The heart of the board is the IDT 77201 NICStAR鈩? which
is an ATM Segmentation And Reassembly (SAR) controller.
The NICStAR鈩?connects directly to the PCI bus, a private
