SDA3302 General Description

Combined with a VCO (tuner) the SDA 3302 device, with four hardware-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 oscillators between 16 and 1300 MHz in increments of 62.5 kHz. The tuning process is controlled by a microprocessor via an I2C bus. The crystal oscillator generates a sinusoidal signal suppressing the higher-order harmonics, which reduces the moiré noise considerably.
