General Description
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.
Key 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).
- 3-pin oscillator for band C.
- Local oscillator buffer output for external synthesizer.
- SAW filter preamplifier with a low output impedance to drive the SAW filter directly.
- Band gap voltage stabilizer for oscillator stability.
- Electronic band swi.
