■ Grounding and Power Supply Decoupling
VD1, VD2, VP, VVD, VSS1, VSS2 and VSS3 should be supplied from analog supply unit with low impedance and be
separated from system digital supply. An electrolytic capacitor 4.7μF parallel with a 0.1μF ceramic capacitor should be
attached to VD1, VD2, VVD, VSS1, VSS2 and VSS3 pin to eliminate the effects of high frequency noise. The 0.1μF
ceramic capacitor should be placed as near to VD1 (VD2, VVD) as possible.
The VP pin must be connected to the Analogue 12V power supply via a 10ohm resistor and with a 0.1µF ceramic
capacitor in parallel with a 1µF electrolytic capacitor to VSS1, as shown in Figure 16.
■ Analog Audio Outputs
The analog outputs are also single-ended and centered on 0V(typ.). The output signal range is typically 2Vrms .
■ Slow Blanking pins
The Slow Blanking Pin must have a 470ohm ±5% series resistor.
