Low-power AM/FM stereo radio for handheld applications
[1]
Programmable frequency range of the synthesizer referred to the antenna input.
[2]
fRF = 100 MHz; fFM(max) = 22.5 kHz; fmod = 1 kHz; τdeemp =50 s.
[3]
The sensitivity at the dummy input is equivalent to EMF in a 75
system.
Conditions: (S+N)/N = 26 dB; L = R; Baud(3dB) = 300 Hz to 15 kHz, A-weighted; fIF = 133.333 kHz.
[4]
Vi2 = 1 mV; fFM(max) = 22.5 kHz.
[5]
Vi2 = 1 mV; L = R; Baud(3dB) = 300 Hz to 15 kHz, A-weighted; fIF = 133.333 kHz.
[6]
Vi2 = 1 mV; f = 75 kHz; with external τdeemp =50 s; Baud(3dB) limited to 15 kHz.
[7]
fRF = 918 kHz; m = 0.3; fmod = 1 kHz; τdeemp =75 s
