Proslic Programmable Cmos Slic/codec With Ringing/battery Voltage Generation

The ProSLIC SI3210 SI3211 SI3212 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 By Unkown
