TDA5630BT Description
TDA5630BT The TDA5630BT is a monolithic integrated circuit that performs VHF and UHF mixer/oscillator functions in TV and VCR cable tuners. With a proper oscillator application and by using a switchable inductor to split the VHF band into two sub-bands, the full VHF/UHF TV bands can be covered. This low-power mixer/oscillator requires a power supply of 9 V and is available in a very small package.
TDA5630BT Key Features
- Balanced mixer with a mon emitter input for band A (single input)
- 2-pin oscillator for band A
- Balanced mixer with a mon base input for band C
- 3-pin oscillator for band C
- Local oscillator buffer output for external prescaler
- SAW filter preamplifier with a low output impedance to drive a SAW filter
- Band gap voltage stabilizer for oscillator stability
- Electronic band switch
TDA5630BT Applications
- Cable tuners for TV and VCR (switched concept for VHF)
- Remended RF bands for Europe: 48.25 to 105.25 MHz, 112.25 to 294.25 MHz and 471.25 to 855.25 MHz
