DATASHEET HC55185 FN4831 Rev 15.00 VoIP Ringing SLIC Family February 9, 2012 The RSLIC-VoIP family of Features ringing subscriber line Onboard Ringing Generation interface circuits (RSLIC) supports analog Plain Old Compatible with Existing HC5518x Devices Telephone Service (POTS) in Low Standby Power Consumption (75V, 65mW) short and medium loop length, wireless and wireline Reduced Idle Channel Noise applications. Ideally suited for remote subscriber units, this family of products offers flexibility to designers with high Programmable Transient Current Limit ringing voltage and low power consumption system Improved Off Hook Software Interface requirements. Integrated MTU DC Characteristics The RSLIC-VoIP family operates to 100V, which translates directly to the amount of ringing voltage supplied to the end Low External Component Count subscriber. With the high operating voltage, subscriber loop Silent Polarity Reversal lengths can be extended to 500 (i.e., 5,000 feet) and Pulse Metering and On Hook Transmission beyond. Tip Open Ground Start Operation Other key features across the product family include: low power consumption, ringing using sinusoidal or trapezoidal Balanced and Unbalanced Ringing waveforms, robust auto-detection mechanisms for when Thermal Shutdown with Alarm Indicator subscribers go on or off hook, and minimal external discrete application components. Integrated test access features are 28 Lead Surface Mount Packaging also offered on selected products to support loopback Reduced Footprint Micro Leadframe Packaging testing as well as line measurement tests. Dielectric Isolated (DI) High Voltage Design There are five product offerings of the HC55185 with each QFN Package Option version providing voltage grades of high battery voltage and - Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat longitudinal balance. The voltage feed amplifier design uses No Leads - Product Outline low fixed loop gains to achieve high analog performance - Near Chip Scale Package Footprint Improves PCB with low susceptibility to system induced noise.
