• Powered using a single 3.3 V supply
• PCM/SPI, ISI and analog interface options
DESCRIPTION
The ProSLIC
®
family of products provides complete analog telephone interfaces ideal for customer
premise equipment (CPE) and enterprise 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.
• Available integrated DAA system side
for FXO
BENEFITS
• Global compliance with single hardware
design

Flexible
The device’s highly programmable feature set provides the flexibility to optimize
performance across the broadest range of customer applications. All SLIC and
codec parameters are 100% configurable using software programmable registers.
Silicon Labs’ API accelerates and simplifies code development with a ready-made
set of functions common to the ProSLIC family.
Cost Effective
The ProSLIC’s complete integration of an analog telephony interface into a single
low-voltage CMOS device enables designers to realize an extremely compact
solution at an attractive price point. Availability of single, and dual channel
devices offers the right balance between size and cost per channel.
