... Philips Semiconductors Phase-locked loop Fig.2 Pinning diagram. FUNCTIONAL DESCRIPTION VCO part The VCO requires one external capacitor (C1) and one or two external resistors ( and R2). Resistor R1 and capacitor C1 determine the frequency range of the VCO. Resistor R2 enables the VCO to have a frequency off-set if required. The high input impedance of the VCO simplifies the design of low-pass filters ...

... Philips Semiconductors Phase-locked loop Phase comparator edge-controlled digital memory network. It consists of four flip-flops, control gating and a 3-state output circuit comprising p and n-type drivers having a common output node. When the p-type or n-type drivers are ON, they pull the output respectively. This type of phase comparator only acts ...
