Bipolar IC

Combined with a VCO (tuner) and a fast divider (dividing ratio 1:64), the ASBC technology component forms a digitally programmable phase-locked loop for television sets with PLL frequency synthesis tuning. The PLL enables crystal-controlled setting of the tuner oscillator frequency for 125 kHz resolution in the TV band III/IV/V. A serial interface facilitates connection to a microprocessor.
