8 / 13 page August 1990 8 Philips Semiconductors Product specification Integrated FM tuner for radio receivers TDA1574T Notes to the characteristics 1. Power gain conversion is equated by the following equation: 2. Voltage gain is equated by the following equation: Wideband threshold (RMS value) (see Figs 3, 4, 5 and 6) at V14 = 0.7 V; V20 = VP/2; I20 = 0 EMF2(rms) − 17 − mV Oscillator output buffer (pin 9) DC output voltage V9 − 6 − V Oscillator output voltage (RMS value) at RL = oo; CL = 2 pF V9(rms) − 110 − mV at RL = 75 Ω V9(rms) 30 50 − mV DC output resistance R9-17 − 2.5 − k Ω Signal purity Total harmonic distortion THD −−15 − dB Spurious frequencies at EMF 1 = 1 V; RS1 = 50 Ω fS −−35 − dB Electronic standby switch (pin 11) Oscillator; linear IF amplifier; AGC Tamb = −40 to + 85 °C Input switching voltage for threshold ON V20 = > VP−3 V V13 0 − 2.3 V for threshold OFF V20 = < 0.5 V V13 3.3 − 23 V Input current at ON condition V13 = 0 V −I13 −− 150 µA at OFF condition V13 = 23 V −I13 −− 10 µA Input voltage I13 = 0 V13 −− 4.4 V PARAMETER CONDITIONS SYMBOL MIN.
