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.

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.

APPLICATIONS
• 2-band TV tuners
• 2-band VCR tuners.
