GENERAL DESCRIPTION
The TDA5330T is a monolithic integrated circuit that performs the band A, band B and band C mixer/oscillator functions in TV and VCR tuners. This device gives the designer the capability to design an economical and physically small 3-band tuner which will be capable of meeting the most stringent requirements e.g. FTZ or FCC. The tuner development time can be drastically reduced by using this device.

FEATUREs
• Balanced mixer with a common emitter input for band A
• Amplitude-controlled oscillator for band A
• Balanced mixer with common base input for band B and C
• Balanced oscillator for band B and C
• Local oscillator buffer output for external prescaler
• SAW filter preamplifier with an output impedance of 100Ω
• Bandgap voltage stabilizer for oscillator stability
• Electronic bandswitch
