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 T elephone 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 500Ω (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 V

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 = 0.795V for -75V devices.

5. Longitudinal Balance is tested per IEEE455-1985, with 368Ω 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 10µs, and 10 x 1000µs 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.
