HC55183, HC55184 FN4519
Rev 8.00
August 10, 2010 Extended Reach Ringing SLIC Family
The RSLIC18в„ў 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 HC55183 and HC55184 family operates up to 75V, and
the HC55185 family operates to 100V, which translates
directly to the amount of ringing voltage supplied to the end
subscriber. With 100V operating voltage, subscriber loop
lengths can be extended up to 500пЃ— (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 …
