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.
