VCCPLL Pin Requirements
To reduce clock skew on the i960 80960Jx processor, the VCCPLL pin for the Phase Lock Loop
(PLL) circuit is isolated on the pinout. The lowpass filter, as shown in Figure 9, reduces noise
induced clock jitter and its effects on timing relationships in system designs. The 4.7 µF capacitor
must be low ESR solid tantalum; the 0.01 µF capacitor must be of the type X7R and the node
connecting VCCPLL must be as short as possible.
