Filter Pin Configuration
The CY7C955 Phase-locked Loop is designed to meet the
Bellcore specifications on jitter generation, jitter transfer, and
jitter tolerance. The highly integrated charge pump design
drastically reduces the complexity of external filter compo-
nents. Only a single 0.47- F non-polar capacitor is needed to
The 1.0- F capacitor should have the following characteristics:

fined in GR-253. Figure 14 describes how to connect the ca-
pacitor across the LF and LFO pins of the CY7C955. The
LF+ pin is to be left unconnected.
