Hout position control circuit

摘要

Disclosed is a HOUT position control circuit used to control the horizontal position of display image in a multisync monitor. The circuit has: a first PLL circuit that is phase-locked with input horizontal synchronous signal; a second PLL circuit that is phase-locked with output of the first PLL circuit; and a circuit for generating a delay between outputs of the first PLL circuit and the second PLL circuit to control the delay amount from the input horizontal synchronous signal to output horizontal drive signal.
