Function
Power On Reset Input
An active Low signal on this pin starts the system initialization. All internal registers
are set to their default values and the serial interface will be reinitialized and the
chip will enter power down mode.
Serial Control Chip Select Input
An active Low signal on this pin enables serial data transfers via SDI and SDO.
Serial Control Clock Input
This pin acts as shift clock signal input for serial control data transfer via SDI and
SDO when CS is active Low and may be asynchronous to all other clock signals.
Serial Control Data Input
This input samples control data bits on the rising edges of the serial clock SCL
when CS is active Low. Depending on the type of transfer 8 or 16 bits are shifted
in.
Serial Control Data Output
This output shifts out control/status data with the falling edge of SCL when CS is
active Low.
Receive PCM Data Input
This input samples PCM data bits on the falling edges of the serial clock SCLK
following a rising edge on the receive strobe signal. After the time when all data
bits have been shifted into the receive shift register all bits are latched into the
receive latch for digital to analogue conversion.
Receive PCM Strobe Input
The signal on this input initiates shifting of serial data into the receive shift register.
It must be synchronized with SCLK. The clock rate is typically 8 kHz. The signal
width determines whether short strobe or long strobe mode is used: A pulse width
of one to two shift clock periods selects short strobe mode. (For further information
see PCM Timing Diagramme ). The strobe signal does not need to be active
throughout the transmission period since an internal bit counter generates the
necessary timing for 8 or16 bit periods depending on the selected output format for
serial PCM reception.
Transmit PCM Strobe Input
This signal on this input initiates shifting of serial data out of the transmit shift
register. It must be synchronized with SCLK. The clock rate is typically 8 kHz. The
signal width determines whether short strobe or long strobe mode is used: A pulse
width of one to two shift clock periods selects short strobe mode. Pulse widths
from 3 clock periods on wards select long strobe mode. The strobe signal does not
need to be active throughout the transmission period since an internal bit counter
generates the necessary timing for 8 or 16 bit periods depending on the selected
output format for serial PCM transmission.
Transmit PCM Data Output
This Tristate output shifts out PCM data from the Codec's A/D converter and is
activated during the transmission of serial data for 8 or 16 transmit clock periods
following a rising edge on the transmit strobe signal. It is updated by the rising
edges of the SCLK clock signal. The output goes back to high impedance after
transmission of 8 or 16 data bits.
