The input to the on-chip oscillator and external
clock input. Components are on chip.
The inverted output of the on-chip oscillator.
A logic ‘1’ applied to this input enables the
DETECT output. A logic ‘0’ will reset
DETECT output to a logic ‘0’.
When a call progress signal is detected, this
output goes to a logic ‘1’.
Signal input. Signals to this pin should be ac
coupled. The dc bias of this pin is set
internally.
The negative supply rail (ground).
Internally generated reference voltage, held at
½V
The positive supply rail. This pin should be
decoupled to V
Internal Connection. Do not make any
connection to these pins.
