9 / 28 page 1997 Feb 24 9 Philips Semiconductors Product specification 5 V VHF, hyperband and UHF mixers/oscillators for TV and VCR 3-band tuners TDA5736; TDA5737 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. Band C oscillator fosc frequency range 0.45 V < Vt < 28 V; notes 1 and 5 485 − 900 MHz fshift frequency shift ∆VP = 5%; note 6 −− 53 kHz fdrift frequency drift with no compensation ∆T=25 °C; NP0 capacitors; note 7 −− 2800 kHz 5 s to 15 mins after switch on; NP0 capacitors; note 8 −− 700 kHz frequency drift with compensation ∆T=25 °C; notes 7 and 9; see Fig.18 −− 1000 kHz 5 s to 15 mins after switch on; notes 8 and 9; see Fig.18 −− 250 kHz Vripple ripple susceptibility of supply voltage (peak to peak value) fosc = 485 MHz; 4.75 V < VP < 5.25 V; see Fig.8 20 −− mV fosc = 900 MHz; 4.75 V < VP < 5.25 V; see Fig.8 18 −− mV Φ N phase noise measured at the IF output at 10 kHz offset; Vo = 105 dBµV 81 −− dBc/Hz LO output ZO output admittance (YP+jωCP)YP = 80 MHz; see Fig.12 − 2.5 − mS YP = 900 MHz; see Fig.12 − 5 − mS CP; see Fig.12 − 0.9 − pF Vo output voltage RL =50 Ω; 0<Vt < 35 V 80 91 100 dB µV SRF spurious signal on LO output with respect to LO output signal RL =50 Ω; 0.2V<Vt <35V; notes 1 and 10 −− −10 dB HLO LO signal harmonics with respect to LO signal RL =50 Ω; 0<Vt < 35 V; note 1 −− −10 dB IF amplifier S22 output reflection coefficient magnitude; see Fig.15 −−16 − dB phase; see Fig.15 − 12 − deg.
