II - MAIN FUNCTIONS
- Detection and extraction of line and frame syn-
chronization pulses from the composite video
signal.
- Horizontal scanning control and synchronization
by two phase-locked loop devices.
- Videoidentification.
- 50or60Hz standardrecognition forverticalscan-
ning.
- Generation of a self-synchronized frame saw-
tooth for 50/60Hz standards.
- Line time constant switching for VCR operation
through an input labeled ”VCR” (Video Cassette
Recorder).
- Control and regulation of a primary-connected
switching power supplyby on-chip controller de-
vicecombining :
an error amplifier
a pulse width modulator synchronized on line
frequency
a start-up and protectionsystem
- OverallTV set protection input
- Frameblanking andsuper sandcastleoutputsig-
nals
- Frameblanking safetyinputfor CRTprotectionin
case of vertical stage failure.
