GENERAL DESCRIPTION
The TDA5636B and TDA5637B are monolithic integrated circuits that perform the mixer/oscillator functions for bands A, B and C in TV and VCR tuners. These low-power mixer/oscillators require a power supply of 9 V and are available in a very small package.
FEATURES
• Balanced mixer with a common emitter input for band A (single input)
• 2-pin oscillator for bands A and B
• Balanced mixer with a common base input for bands B and C (balanced input)
• 4-pin oscillator for band C
• Local oscillator buffer output for external prescaler
• SAW filter preamplifier with a low output impedance to drive the SAW filter directly
• Band gap voltage stabilizer for oscillator stability
• Electronic band switch
• External IF filter between the mixer output and the IF amplifier input
• Pin-to-pin compatible with TDA5636; TDA5637 family (same function with asymmetrical IF output).
APPLICATIONS
• 3-band all channel TV and VCR tuners
• Any standard.
