9 V VHF hyperband and UHF mixer/oscillator
for TV and VCR 3-band tuners
TDA5636B; TDA5637B
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.17) 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; fosc =fRF + 33.4 MHz.
4. Limits are related to the tank circuits used in Fig.17. Frequency bands may be adjusted by the choice of external
components.
5. The frequency shift is defined as the change in oscillator frequency when the supply voltage varies from
VP = 9 to 8.1 V and from VP = 9 to 9.9 V.
6. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
Tamb =25to0 °C and from Tamb = 25 to 50 °C.
7. Switch on drift is defined as the change in oscillator frequency between 5 s and 15 min after switch on.
8. SRF: spurious signal on LO with respect to LO output signal:
RF level = 120 dB
V at fRF < 180 MHz
RF level = 107.5 dB
V at fRF = 180 to 225 MHz
RF level = 97 dB
V at fRF = 225 to 860 MHz.
