CIRCUIT FOR STABILIZING POWER OF VIDEO-CD PLAYER FOR VEHICLE

摘要

PURPOSE: A circuit for stabilizing a power of a video-CD player for vehicle is provided to fit a synchronization of CD part and MPEG part and to prevent a power noise by differently controlling a supplying timing of power fed to the CD part and the MPEG part when the power of video-CD player is repeatedly turned on and off. CONSTITUTION: In feeding a power on signal of high state to an A port unit(10), a first regulator(11) supplies a driving power to a CD part. In feeding the power on signal of high state delayed as a t time(1-seconds) to a B port unit(20), a second regulator(21) supplies the driving power to a MPEG part after delaying a time until clocks such as a BLCK and a LRCK of CD part are output and fed to the MPEG part. The MPEG part synchronizes to an oscillating frequency of 16.934MHz oscillator by decoding the clock such as the BLCK and the LRCK. And the MPEG part processes a video signal without distorting a displayed screen.
