Description
Wireless Local Loop
Voice Over IP
Integrated Access Devices
The ProSLIC™ is a low-voltage CMOS device that integrates SLIC, codec, and
battery generation functionality into a complete analog telephone interface. The
device is ideal for short loop applications such as terminal adaptors, cable telephony,
and wireless local loop. The ProSLIC is powered with a single 3.3 V or 5 V supply.
The Si3210 generates battery voltages dynamically using a software programmable
dc-dc converter from a 3.3 V to 35 V supply; negative high-voltage supplies are not
needed. All high voltage functions are performed locally with a few low cost discrete
components. The device is available in a 38-pin TSSOP and interfaces directly to
standard SPI and PCM bus digital interfaces.
