Bypass and decouple the voltage reference with parallel 10 µF and 0.1 µF capacitors to AGND. Connection Point for External Bias Resistor Analog Power Supply Connected to Analog 5 V Supply Filter Capacitor Connection with Parallel 10 µF and 0.1 µF Capacitors to AGND Left Channel Negative Analog Output Left Channel Positive Analog Output Analog Ground Right Channel Zero Flag Output. This pin goes high when the right channel has no signal input or the DSD mute pattern is detected. Left Channel Zero Flag Output. This pin goes high when the left channel has no signal input or the DSD mute pattern is detected. Mute. Assert high to mute both stereo analog outputs. Deassert low for normal operation. Power Down/Reset. The AD1955 is placed in a reset state and the digital circuitry is powered down when this pin is held low. The AD1955 is reset on the rising edge of this signal. The serial control port registers are reset to the default values. Connect high for normal operation. Serial Control Input, MSB First, Containing 16 Bits of Unsigned Data. Used for specifying control information and channel-specific attenuation. Latch Input for Control Data Clock Input for Control Data. Control input data must be valid on the rising edge of CCLK. CCLK may be continuous or gated. Master Clock Input. Connect to an external clock source. Digital Ground
