Clock Generators target low-skew applications.

Series XRK6977x PLL-based LVCMOS clock generators generate variety of bank frequency ratios and output-to-input frequency ratios from single clock signal source. Each device uses PLL circuit to frequency lock outputs to input reference clock, divider in feedback path then determines frequency of VCO. In addition, each output bank can individually divide down VCO output frequency. Devices accept...
