Objective specification

Low power mixers/oscillators

for satellite tuners

TDA8010M;

TDA8010AM

FEATURES

• Fully balanced mixer with common base input

• Wide input power and frequency range

• One-band 2 pin oscillator

• Local oscillator buffer and prescaler

• SAW filter IF preamplifier with gain control input and

switchable output

• Bandgap voltage stabilizer for oscillator stability

• External IF filter between the mixer output and the IF

amplifier input.

APPLICATIONS

• Down frequency conversion in DBS (Direct

Broadcasting Satellite) satellite receivers.

GENERAL DESCRIPTION

The TDA8010M; TDA8010AM are integrated circuits that

perform the mixer/oscillator function in satellite tuners.

The devices include a gain controlled IF amplifier that can

directly drive two single-ended SAW filters or a differential

SAW filter using a three function switchable output.

They contain an internal LO prescaler and buffer that is

compatible with the input of a terrestrial or satellite

frequency synthesizer. They are also suitable for digital TV

tuners. These devices are available in small outline

packages that give the designer the capability to design an

economical and physically small satellite tuner.
