A5
I
Address Select. A0 = LSB; A5 = MSB Must match
address/command word to enable the serial port.
12
SPS
I
Serial Port Select. Tie to VDD to select the serial port; tie to VSS to
select the hardware mode.
13
MCLK
I
Master Clock. 10 MHz clock for the ADPCM processing engine;
may be asynchronous to SCLK, CLKX, and CLKY.
14
VSS
-
Signal Ground. 0.0 volts.
16
XIN
I
X Data In. Sampled on falling edge of CLKX during selected time
slots.
17
CLKX
I
X Data Clock. Data clock for the X side PCM interface; must be
synchronous with FSX.
18
FSX
I
X Frame Sync. 8 kHz frame sync for the X side PCM interface.
20
XOUT
O
X Data Output. Updated on rising edge of CLKX during selected
time slots.
21
SCLK
I
Serial Data Clock. Used to write to the serial port registers.
22
SDI
I
Serial Data In. Data for onboard control registers; sampled on the
rising edge of SCLK. LSB sent first.
23
CS
I
Chip Select. Must be low to write to the serial port.
24
YOUT
O
Y Data Output. Updated on rising edge of CLKY during selected
time slots.
25
FSY
I
Y Frame Sync. 8 kHz frame sync for the Y side PCM interface.
26
CLKY
I
Y Data Clock. Data clock for the Y side PCM interface; must be
synchronous with FSY.
27
YIN
I
Y Data In. Sampled on falling edge of CLKY during selected time
slots.
28
VDD
-
Positive Supply. 5.0 volts.
