66-MHz PCI clock signal ac parameters
The ac specification consists of input requirements and output responses. The input requirements consists of
setup and hold times, pulse widths, and high and low times. Output responses are delays from clock to signal.
The ac specifications are defined are separately for each clock domain within the PCI2050A.
Figure 1 shows the ac parameters measurements for P_CLK and S_CLK signals.
NOTE: Vt(1)
2.0 V for 5-V clocks; 0.5 VCC for 3.3-V clocks
Vt(2)
1.5 V for 5-V clocks; 0.4 VCC for 3.3-V clocks
Vt(3)
0.8 V for 5-V clocks; 0.3 VCC for 3.3-V clocks
