SL1714
Quadrature Downconverter
Advance Information
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 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.
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.
