9 V VHF, hyperband and UHF mixer/oscillator for TV and VCR 3-band tuners

FEATURES

• Balanced mixer with a common emitter input for band A (single input)

• 2-pin oscillator for bands A and B

• Balanced mixer with a common base input for

bands B and C (balanced input)

• 3-pin oscillator for band C

• Local oscillator buffer output for external synthesizer

• SAW filter preamplifier with a low output impedance to

drive the SAW filter directly

• Band gap voltage stabilizer for oscillator stability

• Electronic band switch.

APPLICATIONS

• 3-band all channel TV and VCR tuners

• Any standard.

GENERAL DESCRIPTION

The TDA5630 and TDA5631 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 9 V and are available in a very small package.

The 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.12, 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 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.12) 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.12. Frequency bands may be adjusted by the choice of external components.

6. The frequency shift is defined for a variation of power supply, first from VP= 9 to 8.1 V, then from VP= 9 to 9.9 V. In both cases, the frequency shift is below the specified value.

7. The frequency drift is defined for a variation of ambient temperature, first from T from T capacitors. Capacitor types C1 to C11, as specified in Fig.12 for non-PLL applications, must be changed to series with other temperature coefficients (e.g. N330, N750 etc.).

8. Switch on drift is the change of oscillator frequency between 5s and 15 min after switch on.

9. The values have been corrected for hybrid and cable losses. The symmetrical output impedance of the hybrid is 100 Ω.

10. Measured with RF input voltage: a) RF voltage = 120 dBµV at fRF< 180 MHz. b) RF voltage = 107.5 dBµV at 180 MHz < fRF< 225 MHz. c) RF voltage = 97 dBµV at 225 MHz < fRF< 860 MHz.
