Audio Negative Voltage Output Pin
22 VEE
O
Connect to ground via a 1.0 μF low ESR (Equivalent Series Resistance) capacitor
over temperature. When this capacitor is polarized, the positive polarity pin should
be connected to the ground pin. Non-polarized capacitors can also be used.
Audio Negative Charge Pump Capacitor Terminal Pin
23 CN
I
Connect to the CP pin via a 1.0 μF low ESR (Equivalent Series Resistance)
capacitor over temperature. When this capacitor is polarized, the positive polarity
pin should be connected to the CP pin. Non-polarized capacitors can also be used.
24 CP
I
Audio Positive Charge Pump Capacitor Terminal Pin
Refer to the CN pin.
Audio Power Supply Pin: 3.13V ~ 3.47V
25 VD1
-
Normally connected to VSS via a 0.1μF ceramic capacitor in parallel with a 4.7μF
electrolytic capacitor.
Video Charge Pump Power Supply Pin: 3.13V ~ 3.47V
26 VD2
- Normally connected to VSS via a 0.1μF ceramic capacitor in parallel with a 4.7μF
electrolytic cap.
Video Negative Charge Pump Capacitor Terminal Pin
27 VCP
I
Connect to the VCN pin via a 1.0 μF low ESR (Equivalent Series Resistance)
capacitor over temperature. When this capacitor is polarized, the positive polarity pin
should be connected to the VCP pin. Non-polarized capacitors can also be used.
28 VCN
I
Video Positive Charge Pump Capacitor Terminal Pin
Refer to the VCP pin.
Analog Ground
- VSS
- The exposed pad on the bottom surface of the package must be connected to the
( Exposed Pad)
ground.
Note: All digital input pins must not be allowed to float.
■Handling of Unused Pin
Unused I/O pins must be connected appropriately.
