The TDA5630 and TDA5631 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. The devices give the designer the capability to design an economical and physically small 3-band tuner.
1. Balanced mixer with a common emitter input for ban (single input) 2. 2-pin oscillator for bands A and B 3. Balanced mixer with a common base input for bands B and C (balanced input) 4. 3-pin oscillator for band C 5. Local oscillator buffer output for external synthesize 6. SAW filter preamplifier with a low output impedance drive the SAW filter directly 7. Band gap voltage stabilizer for oscillator stability 8. Electronic band switch
1. 3-band all channel TV and VCR tuners 2. Any standard.
