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 500 (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.
There are ten product offerings of the ISL5585 providing
various grades of ringing battery voltage and longitudinal
balance.

NOTES:
3. These parameters are controlled via design or process parameters and are not directly tested. These parameters are characterized upon initial
design release and upon design changes which would affect these characteristics.
4. Differential Ringing Gain is measured with VRS = 0.795VRMS for -100V devices, VRS = 0.663 VRMS for -85V devices and VRS = 0.575VRMS
for -75V devices.
5. Longitudinal Balance is tested per IEEE455-1985, with 368 per Tip and Ring terminal.
6. These parameters are tested 100% at room temperature. These parameters are guaranteed not tested across temperature via statistical
characterization and design.
7. The power dissipation is based on actual device measurements and will be less than worst case calculations based on data sheet supply current
limits.
8. Characterized with 2 x 10s, and 10 x 1000s first level lightning surge waveforms (GR-1089-CORE)
9. For Unbalanced Ringing the Tip terminal is offset to 0V and the Ring terminal is centered at Vbh/2 + 0.5V.

Design Equations
Switch Hook Detect
The switch hook detect threshold is set by a single external
resistor, RSH . Equation 1 is used to calculate the value of RSH.
R SH = 600 I SH
(EQ. 1)
The term ISH is the desired DC loop current threshold. The
loop current threshold programming range is from 5mA to
15mA (40k < RSH 100V.

Standard applications will use 49 per side. Protection resistor
values are application dependent and will be determined by
protection requirements.
Design Parameters: Ring Trip Threshold = 76mAPEAK , Switch Hook
Threshold = 12mA, Loop Current Limit = 24.6mA, Synthesize Device
Impedance = (3*66.5k/400 = 498.8, with 49.9 protection
resistors, impedance across Tip and Ring terminals = 599.
