DESCRIPTION
Non-inverting Input of the gain control op-amp.
Inverting Input of the gain control op-amp.
Op-amp Feed-back Gain Control signal. Select the input gain by
connecting this pin and the INN pin with a feed-back resistor. It is
recommended that the op-amp be set to unity gain.
Reference Voltage. Nominally, V
DD
/2 is used to bias the input of the gain
control op-amp.
Operation Mode select. Selects M-mode operation function when high, C-
mode when low.
Ring Detect Input (Schmitt trigger input). Used for ring detection and line
reversal detection. Must maintain a voltage between V
DD
and V
SS
.
Ring RC (Open drain output and schmitt trigger input). Used to set the
time interval from the end of RNGDI pin to the inactive condition of the
RNGON pin. An external resistor must connected to V
DD
and a capacitor
connected to VSS, the time interval is the RC time constant.
Ring detection output (Low active). Indicates the detection of line reversal
and/or ringing.
FSK Data interface MODE select. Sets the FSK data output interface in
mode 0 when low, or in mode 1 when high.
Oscillator Input. A 3.579545 MHz crystal or ceramic resonator should be
connected between this pin and the OSCO pin. May be driven by an
external clock source.
Oscillator Output. A 3.579545 MHz crystal or ceramic resonator should be
connected between this pin and the OSCI pin. Should left open or to drive
another clocked device when an external clock is connected to the OSCI
pin.
Power Supply Ground.
Test pin. Must be connected to V
SS
for normal operation.
Puts the device into a sleep condition (Schmitt input). When high the
device will enter a low power state by disabling the gain control op-amp,
the oscillator and other internal circuits. The function of RNGDI, RNGRC
and the RNGON pins are not affected when the device is in a sleep
condition. This pin is also used to reset the device and must be set low for
normal operation.
FSK Enable. Must be set high when for FSK demodulation. Should be set
low to disable the FSK demodulator and enable the dual tone alert signal
detector when a dual tone alert signal is expected.
