Product specification

5 V VHF, hyperband and UHF mixers/oscillators

for TV and VCR 3-band tuners

TDA5736; TDA5737

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

8. Switch-on drift is defined as the change in oscillator frequency between 5 s and 15 mins after switch on.

9. With thermal compensation, the capacitors of the tank circuits have the following temperature coefficients:

a) In band A: C1, C6 and C8 are N750.

b) In band B: C4, C11, C12, C13 and C36 are N750.

c) In band C: C5, C7, C9 and C10 are N750; C2 is N220 and C3 is NP0.

10. SRF: spurious signal on LO with respect to LO output signal:

a) RF level = 120 dB

b) RF level = 107.5 dB

c) RF level = 97 dB
