these applications is the integrated ringing gener-
ator.
The control interface is a parallel type with open
drain output and 3.3V logiclevels.
The metering pulses are generatedon chip start-
ing from two logic signals (0, 3.3V) one define the
metering pulse frequency and the other the me-
tering pulse duration. An on chipcircuit then pro-
vides the proper shaping and filtering. Metering
pulse amplitude and shaping (rising and decay
time) can be programmed by external compo-
nents. A dedicated cancellation circuit avoid pos-
sible CODEC input saturation due to Metering
pulse echo.
Constant current feed can be set from 20mA to
40mA. Off-hook detection threshold is program-
mable from5mA to 9mA.
The device, developed in BCD100II technology
(100V process), operates in the extended tem-
perature range and integrates a thermal protec-
tion that sets the device in power down when Tj
exceeds140
°
C.
