Preliminary specification
Double mixer/oscillator for TV and VCR
tuners
TDA5332T
GENERAL DESCRIPTION
The TDA5332T is an integrated circuit that performs the mixer/oscillator functions in TV and VCR tuners. This device
gives the designer the capability to design an economical and physically small tuner which will be capable of meeting the
most stringent requirements e.g. FTZ or FCC. The tuner development time can be drastically reduced by using this
device.
Features
Balanced mixer with a common emitter input for band A
Amplitude-controlled oscillator for band A
Balanced mixer with common base input for band B
Balanced oscillator for band B
SAW filter preamplifier with an output impedance of 75
in application
Bandgap voltage stabilizer for oscillator stability
Electronic bandswitch
