Description
TIP Output —Connect to the TIP lead of the subscriber loop.
No Internal Connection —Do not connect to any electrical signal.
RING Output —Connect to the RING lead of the subscriber loop.
Operating Battery Voltage —Si3200 internal system battery supply. Con-
nect SVBATa/b pin from Si3232 and decouple with a 0.1 µ F/100 V filter
capacitor.
High Battery Voltage —Connect to the system ringing battery supply.
Decouple with a 0.1 µ F/100 V filter capacitor.
Low Battery Voltage —Connect to lowest system battery for off-hook oper-
ation driving short loops. An internal diode prevents leakage current when
operating from VBATH.
Ground —Connect to a low-impedance ground plane.
Supply Voltage —Main power supply for all internal circuitry. Connect to a
3.3 V or 5 V supply. Decouple locally with a 0.1 µ F/10 V capacitor.
Battery Voltage Select —Connect to the BATSEL pin of the Si3232 through
an external resistor to enable automatic battery switching.
No Internal Connection —Do not connect to any electrical signal.
No Internal Connection —Do not connect to any electrical signal.
Negative RING Current Control —Connect to the IRINGN lead of the
Si3232.
Positive RING Current Drive —Connect to the IRINGP lead of the Si3232.
Thermal Sensor —Connection to internal temperature-sensing circuit. Con-
nect to THERM pin of Si3232.
