Overview: SL1714
Quadrature Downconverter Advance Information
Supersedes November 1997 issue 1.7 DS4619 - 2.0 April 1998 The SL1714 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 SL1714 is optimised to drive a dual ADC converter such as the VP216. The SL1714 utilises a standard MP16 plastic package, the SL1714C a power MH16 plastic package.
