Low power VHF, UHF and hyperband

mixer/oscillator for TV and VCR 3-band tuners

Product specification

TDA5731M

FEATURES

• Balanced mixer with a common emitter input for band A

(single input)

• 2-pin oscillator for bands A and B

• 3-pin oscillator for band C

• Balanced mixer with a common base input for band B

and C (balanced input)

• Local oscillator buffer output for external synthesizer

• SAW filter preamplifier with a low output impedance to

drive the SAW filter directly

• Electronic band switch.

APPLICATIONS

• 3-band TV tuners

• 3-band TV front-ends

• 3-band VCR tuners

• 3-band VCR front-ends.

GENERAL DESCRIPTION

The TDA5731M is a monolithic integrated circuit that

performs the band A, band B and band C mixer/oscillator

functions in TV and VCR tuners. This low power

mixer/oscillator circuit requires a power supply of 5 V and

is available in a very small package outline. This device

gives the designer the capability to design an economical

and physically small 3-band tuner. The tuner development

time can be drastically reduced by using this device.

In addition, when hyperband is not required, the

TDA5731M may be used in a VHF/UHF tuner with an

appropriate tuned circuit for VHFl and VHFlll in band A and

the tuned circuit of band C for UHF.
