Combined with a VCO (tuner), the MGP 3006X device, with four hard-switched chip addresses, forms a digitally programmable phase-locked loop for use in television sets with PLL-frequency synthesis tuning. The PLL permits precise crystal-controlled setting of the frequency of the tuner oscillator between 16 and 1300 MHz in increments of 62.5 kHz, and, with a 2.4-GHz prescaler 1/2, in the TV-SAT band in increments of 125 kHz. The tuning process is controlled by a microprocessor via an I2C Bus. The I2C Bus noise immunity has been improved by a factor of 10 compared to the SDA 3202-2, and the new crystal oscillator generates a sinusoidal signal, suppressing the higher-order harmonics, which reduces the moiré noise considerably.
