PCI Compliance

The ATF1504AS also supports the growing need in the

industry to support the new Peripheral Component Inter-

connect (PCI) interface standard in PCI-based designs and

specifications. The PCI interface calls for high current driv-

ers 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

ATF1504AS 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 electri-

cal characteristics appear on the next page.
