TDA5630BT

GENERAL DESCRIPTION

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.

The device gives the designer the capability to design an economical and physically small cable tuner.

The tuner development time can be drastically reduced by using this device.

Frequency bands are determined by the external tank circuit. They can be adapted to various standards.

Notes to the characteristics

1. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency.

2. The gain is defined as the transducer gain (measured in Fig.11) plus the voltage transformation ratio of L6 to L7

(10 : 2, 15.4 dB including transformer loss).

3. The input level causing 10 kHz frequency detuning at the LO output. f

4. All s-parameters are referred to a 50 Ω system.

5. Limits are related to the tank circuits used in Fig.11. Frequency bands may be adjusted by the choice of external

components.

6. The frequency shift is defined as the change in oscillator frequency when the supply voltage varies from

VP= 9 to 8.1 V or from VP= 9 to 9.9 V.

7. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from

amb

8. Switch on drift with no compensation is defined as the change of oscillator frequency between 5 s and 15 min after

switch on. All capacitors are NP0.

9. Switch on drift with compensation is defined as the change of oscillator frequency between 5 s and 15 min after

switch on. C5 to C11 are N750; C1, C2 and C4 are N470.

10. The values have been corrected for hybrid and cable losses. The symmetrical output impedance of the hybrid is

100 Ω.
