Extended Reach Ringing SLIC Family
The RSLIC18 family of
ringing subscriber line
interface circuits (RSLIC)
supports analog Plain Old
Telephone Service (POTS) in
short and medium loop length, wireless and wireline
applications. Ideally suited for remote subscriber units, this
family of products offers flexibility to designers with high
ringing voltage and low power consumption system
requirements.
The RSLIC18 family operates to 100V which translates
directly to the amount of ringing voltage supplied to the end
subscriber. With the high operating voltage, subscriber loop
lengths can be extended to 500
(i.e., 5,000 feet) and
beyond.
Other key features across the product family include: low
power consumption, ringing using sinusoidal or trapezoidal
waveforms, robust auto-detection mechanisms for when
subscribers go on or off hook, and minimal external discrete
application components. Integrated test access features are
also offered on selected products to support loopback
testing as well as line measurement tests.
There are five product offerings in the RSLIC18 family:
HC55180, HC55181, HC55182, HC55183 and HC55184.
The architecture for this family is based on a voltage feed
amplifier design using low fixed loop gains to achieve high
analog performance with low susceptibility to system
induced noise.
