MM1109

MITSUMI No-adjustment Sync Separator MM1109 No-adjustment Sync Separator Monolithic IC MM1109 Outline This IC is the same as MM1108, a no-adjustment sync separator IC, with the addition of a composite sync output pin. Features 1. 2. 3. 4. 5. 6. 7. 8. Low current consumption 4.4mA typ. 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 Composite sync signal output pin Package SIP-9B (MM1109XS) Applications 1. TV 2. VCR 3. VCR with camera Equivalent Circuit Diagram MITSUMI No-adjustment Sync Separator MM1109 Pin Description Pin no. 1 2 Pin name VCC SC Internal equivalent circuit diagram Function Power supply voltage pin. Impresses 5V. VCC 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 C.SYNC C. SYNC output pin Outputs composite signal separated from input video signal. 9 H.SYNC H. SYNC output pin Outputs horizontal sync signal synchronized to input video signal, except for v...
