Description
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 VDD/2
The positive supply rail. This pin should be bypassed
to VSS by a capacitor.
Internal Connection. Do not make any connection to
these pins.
