SET OF TWO INTEGRATED CIRCUITS INCLUDING A PLL FOR COLOUR TELEVISION RECEIVERS
摘要
An improved kit of two integrated circuits having a phase-locked loop clock oscillator for use in a color television receiver utilizing digital signal processing is described. The voltage controlled oscillator and the phase discriminator of the phase-locked loop are each located in a different one of the two integrated circuits. The control signals for the voltage controlled oscillator are transferred into it via a two-wire digital bus. External discrete components are eliminated.
