TDA5634T Overview
TDA5634T The TDA5634T is an integrated circuit that performs the UHF mixer/oscillator functions in TV and VCR tuners. This low-power mixer/oscillator requires a power supply of 9 V and is available in a very small package. The device gives the designer the capability to design an economical and physically small tuner.
TDA5634T Key Features
- Balanced mixer with a mon base input
- 4-pin oscillator
- 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
- External IF filter between the mixer output and the IF amplifier input. APPLICATION
