6 / 50 page  6 DS620A1 CS4384 1. PIN DESCRIPTION Pin Name # Pin Description VD 4 Digital Power (Input) - Positive power supply for the digital section. GND 5 31 Ground (Input) - Ground reference. Should be connected to analog ground. MCLK 6 Master Clock (Input) - Clock source for the delta-sigma modulator and digital filters. Table 1 illustrates several standard audio sample rates and the required master clock frequency. LRCK 7 Left Right Clock (Input) - Determines which channel, Left or Right, is currently active on the serial audio data line. The frequency of the left/right clock must be at the audio sample rate, Fs. SDIN1 SDIN2 SDIN3 SDIN4 8 11 13 14 Serial Audio Data Input (Input) - Input for two’s complement serial audio data. SCLK 9 Serial Clock (Input) - Serial clock for the serial audio interface. VLC 18 Control Port Power (Input) - Determines the required signal level for the control port. RST 19 Reset (Input) - The device enters a low power mode and all internal registers are reset to their default settings when low. FILT+ 20 Positive Voltage Reference (Output) - Positive reference voltage for the internal sampling circuits. Requires the capacitive decoupling to analog ground, as shown in the Typical Connection Diagram. VQ 21 Quiescent Voltage (Output) - Filter connection for internal quiescent voltage. MUTEC1 MUTEC234 41 22 Mute Control (Output) - These pins are intended to be used as a control for external mute circuits to prevent the clicks and pops that can occur in any single supply system. AOUT1 AOUT2 AOUT3 AOUT4 AOUT5 AOUT6 AOUT7 AOUT8 39 38 35 34 29 28 25 24 Analog Output (Output) - The full scale analog output level is specified in the Analog Characteristics specification table.
