and digital internal circuits.
Analog Grounds
. Both ground pins must be connected on the circuit board. AGND
serves both analog and digital internal circuits.
Receive PCM Data Input
. The data on this pin is shifted into the device on the fall-
ing edges of MCLK. Sixteen consecutive bits of data (8 bits for channel 0, and
8 bits for channel 1) are entered after the FS pulse has been detected.
Transmit PCM Data Output
. This pin remains in the high-impedance state except
during active transmit time slots. Sixteen consecutive bits of data (8 bits for
channel 0 and 8 bits for channel 1) are shifted out on the rising edge of MCLK. Data
is shifted out on the rising edge of MCLK.
Master Clock Input
. The frequency must be 2.048 MHz or 4.096 MHz. This clock
serves as the bit clock for all PCM data transfer. A 40% to 60% duty cycle is re-
quired.
Digital Ground
. Ground connection for the digital circuitry.
Frame Sync
. This signal is an edge trigger and must be high for a minimum of one
MCLK cycle. This signal must be derived from MCLK. If FS is low for 500
MCLK remains active, then the device fully powers down. An internal pull-down de-
vice is included on FS.
Voltage Common Mode
. 2.4 Vdc.
. This pin should be bypassed to analog ground with at least
