HC55185 Data Sheet February 9, 2012 FN4831.15 VoIP Ringing SLIC Family Features The RSLIC-VoIP family of Onboard Ringing Generation ringing subscriber line Compatible with Existing HC5518x Devices interface circuits (RSLIC) Low Standby Power Consumption (75V, 65mW) supports analog Plain Old Telephone Service (POTS) in Reduced Idle Channel Noise short and medium loop length, wireless and wireline Programmable Transient Current Limit applications. Ideally suited for remote subscriber units, this family of products offers flexibility to designers with high Improved Off Hook Software Interface ringing voltage and low power consumption system Integrated MTU DC Characteristics requirements. Low External Component Count The RSLIC-VoIP family operates to 100V, which translates Silent Polarity Reversal directly to the amount of ringing voltage supplied to the end subscriber. With the high operating voltage, subscriber loop Pulse Metering and On Hook Transmission lengths can be extended to 500 (i.e., 5,000 feet) and Tip Open Ground Start Operation beyond. Balanced and Unbalanced Ringing Other key features across the product family include: low power consumption, ringing using sinusoidal or trapezoidal Thermal Shutdown with Alarm Indicator waveforms, robust auto-detection mechanisms for when 28 Lead Surface Mount Packaging subscribers go on or off hook, and minimal external discrete Reduced Footprint Micro Leadframe Packaging application components. Integrated test access features are also offered on selected products to support loopback Dielectric Isolated (DI) High Voltage Design testing as well as line measurement tests. QFN Package Option There are five product offerings of the HC55185 with each - Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat version providing voltage grades of high battery voltage and No Leads - Product Outline longitudinal balance. The voltage feed amplifier design uses - Near Chip Scale Package Footprint Improves PCB low fixed loop gains to achieve high analog performance Efficiency and has a Thinner Profile with low susceptibility to system induced noise.
