Description
CLOCK
O
NMOS OUT
NMOS open drain output. When dialing, it outputs a series of
pulse trains for DOUT data synchronization. DOUT data is
valid at the falling edge of clock.
VDD
I
Positive power supply, 2.0V~5.5V for normal operation
VSS
I
Negative power supply

KT
O
CMOS OUT
Keytone output pin. Outputs a 1.2kHz tone carrier for 34ms
each time a key is pressed in the pulse mode.
