STLC7550 - LOW POWER LOW VOLTAGE ANALOG FRONT END

Description

The STLC7550 is a single chip Analog Front-end (AFE) designed to implement modems up to 56Kbps.

It has been especially designed for host processing application in which the modulation software (V.34bis, 56Kbps) is performed by the main application processor : Pentium, Risc or DSP processors.
