7 / 42 page [AK4709] MS1319- E-00 2011/07 - 7 - No. Pin Name I/O Function 34 AINRN I Rch Negative Analog Input Pin 35 AINRP I Rch Positive Analog Input Pin 36 AINLN I Lch Negative Analog Input Pin 37 AINLP I Lch Positive Analog Input Pin 38 VEE O Negative Voltage Output Pin Connect to VSS2 with a 1.0 μF capacitor that should have the low ESR (Equivalent 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. 39 CN I Negative Charge Pump Capacitor Terminal Pin Connect to CP with a 1.0 μF capacitor that should have the low ESR (Equivalent Series 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. 40 CP I Positive Charge Pump Capacitor Terminal Pin Connect to CN with a 1.0 μF capacitor that should have the low ESR (Equivalent Series 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 0.1 μF ceramic capacitor in parallel with a 4.7μF electrolytic cap. 43 INT O Interrupt Pin for Video Blanking Normally connected to VVD1(3.3V) through 10k Ω resistor externally. 44 SCL I I2C Control Data Clock Pin 45 SDA I/O I2C Control Data Pin 46 PDN I Power-Down Mode Pin 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. |
