DSP Serial data input pin (Pulldown)
Compatible with MSB first/LSB first 24, 20 and 16 bits
DSP Serial data input pin (Pulldown)
Compatible with MSB first/LSB first 24, 20 and 16 bits
Master clock input pin
Connect a crystal oscillator between this pin and the XTO pin, or input the
external CMOS clock signal XTI pin. The clock frequency
can be selected by the CKS0 and CKS1 pins.
Crystal oscillator output pin
When a crystal oscillator is used, connect it between the XTI pin and this pin.
When the external clock is used, keep this pin open.
Digital Ground
+5 V Digital Power supply
ADC/DAC connection selector pin (Pulldown)
OPCL="L" (Leave open or connect to DVSS.): Connected
OPCL="H": Disconnected
Clock output pin
Outputs the XTI clock.
Allows the output to be set to "L" using the CTRL0 and CTRL1 pins.
LR channel select Clock pin
SMODE="L": Slave mode: Inputs the fs clock.
SMODE="H": Master mode: Outputs the fs clock.
Serial bit clock pin
SMODE="L": Slave mode: Inputs 64 fs or 48 fs clocks.
SMODE="H": Master mode: Outputs 64 fs clocks.
Output data ready pin for microcomputer interface.
Serial data output pin for microcomputer interface (compatible with Hi-Z)
Hi-Z state is obtained when CS =”H".
Data write ready output pin for microcomputer interface (compatible with Hi-Z)
Hi-Z state is obtained when CS =”H”.
