5 / 10 page ![]() May 1992 5 Philips Semiconductors Product specification FM radio circuit TDA7000 A.C. CHARACTERISTICS VP = 4,5 V; Tamb = 25 °C; measured in Fig.4 (mute switch open, enabled); frf = 96 MHz (tuned to max. signal at 5 µV e.m.f.) modulated with ∆f = ± 22,5 kHz; f m = 1 kHz; EMF = 0,2 mV (e.m.f. voltage at a source impedance of 75 Ω); r.m.s. noise voltage measured unweighted (f = 300 Hz to 20 kHz); unless otherwise specified. PARAMETER SYMBOL MIN. TYP. MAX. UNIT Sensitivity (see Fig.3) (e.m.f. voltage) for −3 dB limiting; muting disabled EMF − 1,5 −µV for −3 dB muting EMF − 6 −µV for S/N = 26 dB EMF − 5,5 −µV Signal handling (e.m.f. voltage) for THD < 10%; ∆f = ± 75 kHz EMF − 200 − mV Signal-to-noise ratio S/N − 60 − dB Total harmonic distortion at ∆f = ± 22,5 kHz THD − 0,7 − % at ∆f = ± 75 kHz THD − 2,3 − % AM suppression of output voltage (ratio of the AM output signal referred to the FM output signal) FM signal: fm = 1 kHz; ∆f = ± 75 kHz AM signal: fm = 1 kHz; m = 80% AMS − 50 − dB Ripple rejection ( ∆V P = 100 mV; f = 1 kHz) RR − 10 − dB Oscillator voltage (r.m.s. value) at pin 6 V6-5(rms) − 250 − mV Variation of oscillator frequency with supply voltage ( ∆V P = 1 V) ∆f osc − 60 − kHz/V Selectivity S+300 − 45 − dB S−300 − 35 − dB A.F.C. range ∆f rf −± 300 − kHz Audio bandwidth at ∆V o = 3 dB measured with pre-emphasis (t = 50 µs) B − 10 − kHz A.F. output voltage (r.m.s. value) at RL = 22 kΩ Vo(rms) − 75 − mV Load resistance at VP = 4,5 V RL −− 22 k Ω at VP = 9,0 V RL −− 47 k Ω |
