ATF1502AS_05 数据手册

PCI Compliance

The ATF1502AS also supports the growing need in the industry to support the new Peripheral

Component Interconnect (PCI) interface standard in PCI-based designs and specifications.

The PCI interface calls for high current drivers, which are much larger than the traditional TTL

drivers. In general, PLDs and FPGAs parallel outputs to support the high current load required

by the PCI interface. The ATF1502AS allows this without contributing to system noise while

delivering low output to output skew. Having a programmable high drive option is also possible

without increasing output delay or pin capacitance. The PCI electrical characteristics appear

on the next page.
