VoIP Ringing SLIC Family
FN4831
Rev 15.00
February 9, 2012
The RSLIC-VoIP 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 RSLIC-VoIP 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 of the HC55185 with each
version providing voltage grades of high battery voltage and
longitudinal balance. The voltage feed amplifier design uses
low fixed loop gains to achieve high analog performance
with low susceptibility to system induced noise.

NOTES:
1. Add "96" suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-
020.
3. For Moisture Sensitivity Level (MSL), please see device information page for HC55185. For more information on MSL please see tech brief
TB363.
4. Reference “Special Considerations for the QFN Package” on page 8.
