TDA5636
Description
The TDA5636 and TDA5637 are monolithic integrated circuits that perform the mixer/oscillator functions for bands A, B and C in TV and VCR tuners.
Key Features
- 2-pin oscillator for bands A and B
- 4-pin oscillator for band C
- Local oscillator buffer output for external prescaler
- SAW filter preamplifier with a low output impedance to drive a 75 Ω load
- Band gap voltage stabilizer for oscillator stability
- Electronic band switch
- External IF filter between the mixer output and the IF amplifier input
- 3-band all-channel TV and VCR tuners
- Any standard. TDA5636; TDA5637
