Philips Semiconductors
Low power VHF, UHF mixer/oscillator
for TV and VCR 2-band tuners
Preliminary specification
TDA5732M
FEATURES
• Balanced mixer with a common emitter input for band A
• 2-pin oscillator for band A
• Balanced mixer with a common base input for band C
• 4-pin oscillator for band C
• Local oscillator buffer output for external prescaler
• SAW filter preamplifier with a low output impedance of
75 Ω
• Band gap voltage stabilizer for oscillator stability
• Electronic band switch
• External IF filter connected between the mixer output
and the IF amplifier input.
DESCRIPTION
The TDA5732M is a monolithic integrated circuit that
performs VHF I, VHF III, hyperband and UHF
mixer/oscillator functions in TV and VCR tuners. This
low-power mixer/oscillator requires a power supply of 5 V
and is available in a very small package.
The device gives the designer the capability to design an
economical and physically small 2-band tuner.
The tuner development time can be drastically reduced by
using this device.
APPLICATIONS
• 2-band TV tuners
• 2-band VCR tuners.
