Specified with 30 pF load tPCIHAOV PCLK high to all PCI output signals valid 1 10 ns a, b b. Need to use 4 ns of the PCI propagation delay tPCIHAOZ PCLK high to all PCI outputs tri-state 2 14 ns a tPCIHAON PCLK high to all PCI outputs on 2 ns a tBIVPCIH Bused input signals valid to PCLK high 3 ns c c. NOTPREQ[0:3] and NOTPGNT[0:3] are point to point signals and have different input setup times to bussed signals. All other synchronous signals are bussed. tPIVPCIH Point-to-point input signals valid to PCLK high 5 ns b tPCIHAIX All PCI input signals hold after PCLK high 2 ns Table 25: PCI AC timings Tri-state outputs PCLK Outputs tPCIHAOV tPCIHAON tPCIHAOZ Inputs: bussed tPCIHAIX tBIVPCIH Inputs: point-to-point tPIVPCIH tPCIHPCIH |
