Latest Patents

Sakura's latest patents include a PLL circuit and a digital signal reproducing apparatus. The PLL circuit is designed to function as a reproducing clock forming circuit within a digital signal reproducing apparatus. This circuit is notable for its robustness against noise and its stable characteristics. The phase comparator outputs are presented as balanced differential signals, which are then supplied to a loop filter. The output from the loop filter is directed to the control voltage input terminals of a voltage-controlled oscillator (VCO) in the form of balanced signals. This design allows for the cancellation of in-phase noise components present in the control voltages. Additionally, the time constants of the loop filter can be adjusted using bipolar transistors, ensuring that the balance of the signals remains intact.

Another significant patent involves a circuit for processing color video signals. This circuit is utilized in video tape recorders to process two chrominance component signals that have been time-compressed and recorded in a cyclic manner. The circuit effectively expands these signals back into two series of chrominance signals during reproduction. Through digital processing, the circuit detects correlations between the current signal and the previous signal, outputting an arithmetical mean when a correlation is found and the current signal exceeds a reference level.
