Overview: SL1711
Quadrature Downconverter Preliminary Information
Supersedes November 1996 version, DS4032 - 1.6 DS4032 - 4.0 October 1997 The SL1711 is a quadrature downconverter, intended primarily for application in professional and consumer digital satellite tuners. The device contains all elements necessary, with the exception of external local oscillator tank to form a plete system operating at standard satellite receiver intermediate frequencies. It is intended for use with external carrier recovery. The device includes a low noise RF input amplifier, a reference VCO with prescaler output buffer and In-phase and Quadrature mixers with baseband buffer amplifiers containing AGC gain control. The SL1711 is optimised to drive a dual ADC converter such as the VP216.
