Power-Down Mode Pin
I When at “L”, the AK4703 is in the power-down mode and is held in reset.
The AK4703 should always be reset upon power-up.
O Composite Output Pin for RF modulator
O Composite/Luminance Output Pin for VCR
O Fast Blanking Output Pin for TV
O MONO Analog Output Pin
Power Supply Pin, 12V
- Normally connected to VSS with a 0.1µF ceramic capacitor in parallel with a
10µF electrolytic cap.
Common Voltage Pin
O Normally connected to VSS with a 0.1µF ceramic capacitor in parallel with a
10µF electrolytic cap.
Audio Common Voltage Pin
O Normally connected to VSS with a 0.1µF ceramic capacitor in parallel with a
10µF electrolytic cap. The caps affect the settling time of audio bias level.
O Common Voltage Output Pin
I TBD
Note: All input pins should not be left floating.
Pin layout is TBD.
