3 AINL2 I ADC single-ended analog Lch input pin No.2
4 AINR1 I ADC single-ended analog Rch input pin No.1
5 AINL1 I ADC single-ended analog Lch input pin No.1
6 VREFH I Analog Reference voltage input pin.
Normally connect to AVDD (pin 7) and connect 0.1mF and 10mF capacitors between this pin and AVSS.
7 AVDD - Power supply pin for analog section 3.3V (typ)
8 AVSS - Analog ground 0V
9 DVSS - Ground pin for digital section 0V
10 DVDD - Power supply pin for digital section 3.3V (typ)
11 XTI I Master clock input pin
Connect a crystal oscillator between this pin and the XTO pin or input the external CMOS clock signal XTI pin.
12 XTO O Crystal oscillator output pin
When a crystal oscillator is used it should be connected between XTI and XTO.
When the external clock is used keep this pin open
13 CLKO O Clock output pin Outputs the XTI clock. Allows the output to be set to "L" by control register setting.
14 JX I External condition jump pin (Pull down)
15 SMODE I Slave/master mode selector pin
Set LRCLK and BITCLK to input or output mode.
SMODE-"L": Slave mode (These are set to input mode.)
SMODE-"H": Master mode (These are set to output mode.)
16 LRCLK I/O LR channel select Clock pin
SMODE-"L": Slave mode : Inputs the fs clock.
SMODE-"H": Master mode : Outputs the fs clock.
17 BITCLK I/O Serial bit clock pin
SMODE-"L": Slave mode : Inputs 64 fs or 48 fs clocks.
SMODE-"H": Master mode : Outputs 64 fs clocks.
18 SDIN I DSP Serial data input pin (Pull down)
Compatible with MSB/LSB justified 24 20 and 16 bits.
19 SDINA I DSP Serial data input pin (Pull down)
Leave opens or connect to DVSS at using the internal ADC.
Compatible with MSB justified 24 bits.
