Open collector output Built-in 3V regulator handles power supply ripple Built-in capacitor for vertical sync separation Time from vertical signal to H. SYNC output re-sync reduced (relative to LVA519) Supports both PAL and NTSC formats Sync separation level can be adjusted with external constants Package SOP-8C (MM1108XF) SIP-8A (MM1108XS) DIP-8B (MM1108XD) Applications 1. TV 2. VCR 3. VCR with camera Block Diagram MITSUMI No-adjustment Sync Separator MM1108 Pin Description Pin no. 1 2 Pin name VCC SC Internal equivalent circuit diagram Function Power supply voltage pin. Impresses 5V. VCO integration pin Free run frequency determined by external capacitor between Pin 2 and GND, and external resistor between Pin 3 and GND. 3 VCO VCO input pin Pin 4 output is input via external loop filter. 4 LPF Phase comparator output pin. 5 6 GND VIN GND Signal input pin Inputs video signal. 7 V.SYNC V. SYNC output pin Outputs vertical sync signal separated from input video signal. 8 H.SYNC H. SYNC output pin Outputs horizontal sync signal synchronized to input video signal, except for vertical feedback interval. For no signal, outputs free run frequency horizontal sync signal.
