October 21, 2004 3.3V Ringing SLIC Family for Voice Over Broadband (VOB)
The 3.3V family of ringing subscriber line interface circuits
(SLIC) supports analog Plain Old Telephone Service
(POTS) in short and medium loop length, wireless and
wireline voice over broadband applications. Ideally suited for
customer premise equipment, this family of products offers
flexibility to designers with high ringing voltage and low
power consumption system requirements. Features The ISL5585 family is capable of operating with 100V ringing
battery supply, which translates directly to the amount of
ringing voltage supplied to the subscriber. With the high
operating voltage, subscriber loop lengths can be extended
to 500пЃ— (i.e., 5,000 feet) and beyond, allowing this family to
serve emerging Fiber In The Loop (FITL) markets. Improved Off Hook Software Interface Other key features across the product family include: 3.3V
VCC operation, 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. …
