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™, which is an ATM Segmentation And Reassembly (SAR) controller. The NICStAR™ connects directly to the PCI bus, a private |
