PIN DEFINITION
ZONE 2 ANALOG INPUTS
Zone 2 Analog Inputs
This is the Zone 2 analog input. The Z2_AD_R,L are independent analog inputs for the second audio
zone. The inputs are selected when the amplifier is configured for Mode 2 and the Z2_AD input is Set
High. See Chapter 5 for additional information.The A/D convertor is fixed at a 48kHz sample rate with a
2.0V rms input level.
DIGITAL AUDIO INPUTS
Master System Clock
This pin is the master clock input for the primary channels on SDI[4:1]. The master clock must be an
integer multiple of the LRCLK frequency. The default master clock is 12.288 MHz which corresponds to a
48 kHz sample rate (Fs) * 256. The MCLK is a 3.3 volt input.
Left/Right Clock
This pin is the framing clock for the primary channels on SDI[4:1]. The serial input data is transmitted as
two channels every sample rate period. The LRCLK determines the start of each data pair. The LRCLK
frequency determines the input sample rate (Fs). The LRCLK is a 3.3 volt input.
Shift Clock
This pin is the Shift Clock input for the primary channels on SDI[4:1]. The serial clock is used to frame
each input bit of the serial input data. The shift clock frequency is typically 64*Fs. The SCLK is a 3.3 volt
input.
Serial Data Input
These pins are the Serial Data input for the primary channels. Serial Data is arranged as four left/right
inputs. The input format options are I
lengths are available. The SDI pins are 3.3 volt inputs. Note that input channel 8 is not used.
