The ProSLIC family of products provides complete analog telephone interfaces ideal for

customer premise equipment (CPE), enterprise and central office applications. These

highly-integrated circuits offer global compliance using a single hardware design and

bill-of-materials while reducing the PCB size and cost per channel. Fully programmable

parameters such as two-wire ac impedance, ring amplitude, ring waveshape and dc linefeed

characteristics are provided via a programmable DSP based architecture that provides the

flexibility and performance necessary to address the most demanding customers and service

providers. These combined SLIC and codec solutions integrate a comprehensive set of

telephony features including DTMF generation/decoding, FSK caller ID generation, GR-909

loop diagnostics, pulse metering and battery switching control. Select models include an

integrated dc-dc controller that continuously adapts to the line voltage to minimize thermal

dissipation and maximize power efficiency. All devices are powered using a single 3.3 V

supply and can be controlled using a standard PCM/SPI or GCI digital interface.
