QUICK REFERENCE DATA

GENERAL DESCRIPTION

The TDA5736 and TDA5737 are monolithic integrated circuits that perform the mixer/oscillator functions for bands A, B and C in TV and VCR tuners. These low power mixer/oscillators require a power supply of 5 V and are available in a very small package.

These devices give the designer the capability to design an economical and physically small 3-band tuner.

They are suitable for European standards, as illustrated in Fig.17, with the following RF bands: 48.25 to 168.25 MHz, 175.25 to 447.25 MHz and 455.25 to 855.25 MHz. With an appropriate tuned circuit, they are also suitable for NTSC all channel tuners (USA and Japan).

The tuner development time can be drastically reduced by using these devices.

Notes

1.−20 °C < Tamb < +80 °C; 4.5 V < VP < 5.5 V.

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

3.The gain is defined as the transducer gain (measured in Fig.17) plus the voltage transformation ratio of L7 to L8 (10 : 2, 15.4 dB including transformer loss).

4.The input level causing 10 kHz frequency detuning at the LO output. fosc = fRF + 33.4 MHz.

5.Limits are related to the tank circuits used in Fig.17. 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 = 5 to 4.75 V and from VP = 5 to 5.25 V.
