... DESIGN CONSIDERATIONS Distortion Motorola’s MC141540 has a built–in PLL for multi–system application. Pin 2 voltage is dc–based for the internal VCO in the PLL. When the input frequency (HFLB) to Pin 5 in- creases, the VCO frequency will increase accordingly. This forces the PLL to a higher locked frequency output. The fre- quency should be equal to 320 x HFLB ...
