... This block detects the V-SERATION interval in the GLSYNC input and generates a vertical reset (VR) pulse with 0 the start of that interval. It then issues no pulses for 256 H (NTSC) or 304 H (PAL) after this VR pulse. GLSYNC VR 2.2µs ( NTSC ) 1.8µs ( PAL ) 14.0µs ( NTSC ) 11.2µs ( PAL ) Vertical reset pulse timing chart MN6761S ...

... MN6761S 3. Subcarrier synchronization block This block converts the SC1 output from the synchronizing signal generator into four signals with the same frequency as the burst subcarrier, but different phases. In this phase-locked loop circuit, the phase of GLBSC is compared with the phase selected by 2 bits (SCPSW1 and SCPSW2). ...
