Philips Semiconductors
Low power mixers/oscillators
for satellite tuners
Objective specification
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.
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.
APPLICATIONS
• Down frequency conversion in DBS (Direct
Broadcasting Satellite) satellite receivers.
