IRDY and TRDY The rising edge of CLK is used as the only active clocking edge all other signals are used to properly gualify the acguisition of data PCI32 MN XXX 18 Doc Rev 1 10 APPENDIX B Considerations B 1 PCI Loading It must be noted that the NEX PCI32 Bus Adapter does not provide any buffering of the PCI backplane signals This was a conscious design decision that was made by balancing the tradeoffs of possible backplane loading versus signal acquisition accuracy By not introducing signal buffers it is possible using the NEX PCI32 adapter to see the exact timing relationships and signal waveforms from the backplane It is also much easier to connect pattern generators to the backplane since buffer direction is not a concern It is believed that the signal loading of the TLA600 700 or 92A96 acquisition cards is low enough so that PCI signal degradation will not occur The NEX PCI32 Adapter Board was designed so that the run lengths for critical signals and those with the highest activity levels such as the address data bus are as short as possible This should help greatly in retaining signal integrity B 2 Patch Areas If signal loading or reflection does become a concern the capability exists to add series resistors to any PCI signal Patch areas have been provided next to each TLA600 700 A96 connector consisting of two rows of plated through holes These areas outlined on the silk screen and labeled as Nxx are suit
