stlc1511 is a new wide dynamic range analog front end chip from st. it uses a 14-bit nyquist rate da converter and a programmable gain amplifier. it supports 0~-32db transmit gain and 0~40db receive gain. it integrates a phase-locked loop with an external LC or crystal oscillator. the power consumption is only 300mw.
The STLC1511 is a G.lite BICMOS Analog Front-End (AFE) circuit designed for use in both central office and customer premise modems. It connects a digital modem chip with loop driver and hybrid balance circuits to implement a complete G.992.2 DMT modem solution. The device is available in a 64-pin TQFP package.
