FM DemodulatorCD 4046 CMOS Phase-Lock Loop (PLL) integrated circuitPreliminary work1.Determine the PLL component parameters for a centre frequency of 470 kHz by carefullyexamining the data sheet.Given the value of fo =470KHzfrom the Data sheetfo=1/2 fmaxfmax =2*fo =2*470KHz =960KHzfmax =fo+fL Therefore fL= fmax –fo =960KHz-470KHz =490KHzfmin= fo-fL =470KHz-490KHz =20KHz
