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.
