Hardware
The Holt HI-6130 PCIe interface card consists of three main IC components shown below in the Block
Diagram. The PEX 8311 is a PCI Express-to-Generic Local Bus bridge and provides the interface between
the PCIe slot and the local bus (LB). A CPLD translates the LB signals into CSn, RDn and WRn strobe
signals for the HI-6130 timings. The CPLD also provides other GPIO and glue logic. A shared single
50MHz oscillator module provides the clock for the PEX8311 local bus, CPLD and the HI-6130. The HI-
6130 must be clocked at 50MHz.
