Intersil HC55185 VoIP Ringing SLIC方案
The RSLIC-VoIP family of ringing subscriber line interface circuits (RSLIC) supports analog Plain Old Telephone Service (POTS) in short and medium loop length, wireless and wireline applications. Ideally suited for remote subscriber units, this family of products offers flexibility to designers with high ringing voltage and low power consumption system
requirements.
The RSLIC-VoIP family operates to 100V which translates directly to the amount of ringing voltage supplied to the end subscriber. With the high operating voltage, subscriber loop
lengths can be extended to 500Ω (i.e., 5,000 feet) and beyond.
Other key features across the product family include: low power consumption, ringing using sinusoidal or trapezoidal waveforms, robust auto-detection mechanisms for when ..
