FEATURES
GENERAL DESCRIPTION
·
Balanced mixer with a common emitter input for band A
(single input)
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.
·
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
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.
·
Electronic band switch.
APPLICATIONS
·
3-band TV tuners
·
3-band TV front-ends
·
3-band VCR tuners
·
3-band VCR front-ends.
