 * Take a deep breath, math(ematics) ahead
 * The 25 mhz oscillator is multiplied by 35 to run the vco at 875 mhz
 * This is divided by a number to generate different frequencies.
 * If we divide it by 875, we will get 1 mhz signal
 * So, if the vco is shifted up by 875 hz, the generated frequency of 1 mhz is shifted by 1 hz (875/875)
 * At 12 Mhz, the carrier will needed to be shifted down by 12 hz for every 875 hz of shift up of the vco
