Si3211

*Note: Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional operation should be restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The ProSLIC™ Si3211 is a low-voltage CMOS device that integrates SLIC, codec, and battery generation functionality into a complete analog telephone interface. The Si3211 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 Si3211 is available in a 38-pin TSSOP and interfaces directly to standard SPI and PCM bus digital interfaces.
