P
Positive power supply input for the digital section. VCCA,
VCCP AND VCC must be connected together.
CO
16
19
DO
Control data output.
TX
17
20
DO
Transmit data output. Data is shifted out on this during the
assigned transmit slots. Otherwise, TX is on high impedance
state.
GND
18
21
G
Ground for the digital section.
FS
19
24
DI
Frame sync input. This 8kHz signal defines the start of the TX
and RX frames.
