TDA9887 IF-PLL demodulator circuit
Using the TDA9887 integrated circuit can be designed a very simple IF-PLL demodulator circuit with FM radio .
This TDA9887 IF-PLL demodulator circuit with FM radio circuit is very simple, requiring few external electronic parts.
TDA9887 IC and must be powered from a 5 volts DC power supply .
The IC is an alignment-free multistandard (PAL, SECAM and NTSC) vision and sound IF signal PLL demodulator for positive and negative modulation, including sound AM and FM processing. A special function is implemented for the demodulation of FM radio signals (fRIF = 10.7 MHz).
