Description
I Oscillator Input and Output pins
The time base for the NT91315XL
is a crystal controlled on-chip
oscillator. It is completed by
connecting a 3.58 MHz crystal or
ceramic resonator between the
OSCI and OSCO pins
Power supply pins
These devices are designed to
operate from 2.0V to 5.5V
O Tone dialing output
When a valid keystroke is detected
in DTMF mode, appropriate low
group and high group frequencies
are generated, which hybridize the
dual tone output. Tone output is in
the OFF state when in PULSE
mode
O Dialing transmission mute output
This is an N-channel open drain
output. The XMUTE is normally
OFF. During pulse or DTMF
dialing, this output is ON
O Dialing pulse output
This is an N-channel open drain
output. The normal output will be
ON during break and OFF during
make in the PULSE DIALING
mode
