I Lch Negative Analog Input Pin
I Lch Positive Analog Input Pin
Negative Voltage Output Pin
Connect to VSS2 with a 1.0μF capacitor that should have the low ESR (Equivalent
O
Series Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the VSS2 pin. Non polarity capacitors
can also be used.
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0μF capacitor that should have the low ESR (Equivalent Series
I Resistance) over all temperature range. When this capacitor has the polarity, the
positive polarity pin should be connected to the CP pin. Non polarity capacitors can
also be used.
Positive Charge Pump Capacitor Terminal Pin
Connect to CN with a 1.0μF capacitor that should have the low ESR (Equivalent Series
I Resistance) over all temperature range. When this capacitor has the polarity, the
positive polarity pin should be connected to the CP pin. Non polarity capacitors can
also be used.
41 VSS2
- Charge Pump Ground Pin , 0V
42 VD2
Charge Pump Power Supply Pin: 3.13V ~ 3.47V
- Normally connected to VSS2 with a 0.1μF ceramic capacitor in parallel with a 4.7μF
electrolytic cap.
43 INT
44 SCL
45 SDA
46 PDN
O
Interrupt Pin for Video Blanking
Normally connected to VVD1(3.3V) through 10kΩ resistor externally.
I I²C Control Data Clock Pin
I/O I²C Control Data Pin
Power-Down Mode Pin
I
When at “L”, the AK4709 is in the power-down mode and is held in reset. The
AK4709 should always be reset upon power-up.
47 VCRVOUT O Composite/Luminance Output Pin for VCR
48 TVFB
O Fast Blanking Output Pin for TV
Note: SCL, SDA, PDN pins should not be left floating.
