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 complete 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.
