GENERAL DESCRIPTION

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.
The tuner development time can be drastically reduced by using this device.
The frequency band is determined by the external tank circuit. It can be adapted to various standards.
121 dBµV
Note
1. The limits are related to the tank circuits used in Fig.7 and the intermediate frequency. Frequency bands may be adjusted by the choice of external components.

Notes
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.7) plus the voltage transformation ratio of L3 to L2
(10 : 2, 15.4 dB including transformer loss).
3. The input level causing 10 kHz frequency detuning at the LO output; f
osc=fRF
+ 33.4 MHz.
4. All S-parameters are referred to a 50 system.
5. Measured with RF input voltage of 97 dBµV at 430 MHz < fRF< 860 MHz.
6. Limits are related to the tank circuits used in Fig.7. Frequency bands may be adjusted by the choice of external
components.
7. 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.
8. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
T
=25°C to 0 °C or from T
amb
=25°Cto50°C. Without compensation, the capacitors C11 to C15 are NP0.
amb
9. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
T
=25°C to 0 °C or from T
amb
=25°Cto50°C. With compensation, the capacitors C11 to C14 are N750 and
amb
C15 is N470.
10. Switch on drift is defined as the change in oscillator frequency between 5 s and 15 min after switch on.
