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 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

Quadraturemixerswithbasebandbufferamplifierscontaining

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.
