STLC3065
DESCRIPTION (continued)
MOS switch.
The self generated battery voltage tracks the line
resistance. In this way the power dissipation in-
side the device is low enough to allow the use of
small SMD package (TQFP44).
Other useful characteristics for application in the
WLL environment are the integrated ringing gen-
erator and the dual two wire port that allows to
drive two different terminal equipment whether
the transmission is voice or data. When one port
is transmitting the other one is idle.
The control interface is a parallel type with open
drain output and 3.3V logic levels.
The metering pulses are generated on chip start-
ing from two logic signals (0, 3.3V) one defines
the metering pulse frequency and the other the

metering pulse duration. An on chip circuit then
provides the proper shaping and filtering.
Metering pulse amplitude and shaping (rising and
decay time) can be programmed by external com-
ponents. A dedicated cancellation circuit avoid
possible CODEC input saturation due to Metering
pulse echo.
Constant current feed can be set from 20mA to
40mA.
Off-hook detection threshold is programmable
from 5mA to 9mA.
The device, developed in BCD100II technology
(100V process), operates in the extended tem-
perature range and integrates a thermal protec-
tion that set the device in power down when Tj
exceeds 140°C.
