ISL5585
3.3V Ringing SLIC Family for Voice Over Broadband (VOB)
FN6026
Rev 6.00
October 21, 2004
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.
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 500(i.e., 5,000 feet) and beyond, allowing this family to
serve emerging Fiber In The Loop (FITL) markets.
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.
There are ten product offerings of the ISL5585 providing
various grades of ringing battery voltage and longitudinal
balance.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination
finish, which are 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-020C.
