DATASHEET HC55183, HC55184 FN4519 Rev 8.00 Extended Reach Ringing SLIC Family August 10, 2010 The RSLIC18 family of ringing subscriber line interface Features circuits (RSLIC) supports analog Plain Old Telephone Battery Operation to 75V Service (POTS) in short and medium loop length, wireless Low Standby Power Consumption of 50mW and wireline applications. Ideally suited for remote subscriber units, this family of products offers flexibility to Peak Ringing Amplitude 95V, 5 REN designers with high ringing voltage and low power Sinusoidal or Trapezoidal Ringing Capability consumption system requirements. Integrated CODEC Ringing Interface The HC55183 and HC55184 family operates up to 75V, and Integrated MTU DC Characteristics the HC55185 family operates to 100V, which translates Low External Component Count directly to the amount of ringing voltage supplied to the end Pulse Metering and On Hook Transmission subscriber. With 100V operating voltage, subscriber loop lengths can be extended up to 500 (i.e., 5,000 feet) and Tip Open Ground Start Operation beyond. Thermal Shutdown with Alarm Indicator Other key features across the product family include: low 28 Lead Surface Mount Packaging power consumption, ringing using sinusoidal or trapezoidal Dielectric Isolated (DI) High Voltage Design waveforms, robust auto-detection mechanisms for when HC55183 subscribers go on or off hook, and minimal external discrete - Integrated Battery Switch application components. Integrated test access features are - 45dB Longitudinal Balance also offered on selected products to support loopback HC55184 testing as well as line measurement tests. - Integrated Battery Switch There are 2 product offerings in the RSLIC18 family: - Silent Polarity Reversal HC55183 and HC55184. The architecture for this family is - 45dB Longitudinal Balance based on a voltage feed amplifier design using low fixed loop Pb-Free (RoHS Compliant) gains to achieve high analog performance with low susceptibility to system induced noise.
