DATASHEET ISL5585 FN6026 Rev 6.00 3.3V Ringing SLIC Family for Voice Over Broadband (VOB) October 21, 2004 The 3.3V family of ringing subscriber line interface circuits Features (SLIC) supports analog Plain Old Telephone Service 3.3V Operation (POTS) in short and medium loop length, wireless and wireline voice over broadband applications. Ideally suited for Onboard Ringing Generation customer premise equipment, this family of products offers Low Standby Power Consumption (75V, 65mW) flexibility to designers with high ringing voltage and low Programmable Transient Current Limit power consumption system requirements. Improved Off Hook Software Interface The ISL5585 family is capable of operating with 100V ringing battery supply, which translates directly to the amount of Integrated MTU DC Characteristics ringing voltage supplied to the subscriber. With the high Low External Component Count operating voltage, subscriber loop lengths can be extended to 500 (i.e., 5,000 feet) and beyond, allowing this family to Silent Polarity Reversal serve emerging Fiber In The Loop (FITL) markets. Pulse Metering and On Hook Transmission Other key features across the product family include: 3.3V Tip Open Ground Start Operation V operation, low power consumption, ringing using CC Balanced and Unbalanced Ringing sinusoidal or trapezoidal waveforms, robust auto-detection mechanisms for when subscribers go on or off hook, and Thermal Shutdown with Alarm Indicator minimal external discrete application components. 28 Lead Surface Mount Packaging Integrated test access features are also offered on selected products to support loopback testing as well as line QFN Package: measurement tests. - Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat No Leads - Package Outline There are ten product offerings of the ISL5585 providing - Near Chip Scale Package footprint, which improves various grades of ringing battery voltage and longitudinal PCB efficiency and has a thinner profile balance.
