... DESIGN CONSIDERATIONS Distortion Motorola’s MC141543P has a built–in PLL for multi–sys- tem application. Pin 2 voltage is dc–based for the internal VCO in the PLL. When the input frequency (HFLB) to Pin 5 increases, the VCO frequency will increase accordingly. This forces the PLL to a higher locked frequency output. The fre- quency should be equal to 320/480/640 x HFLB (depending on resolution) ...
