... PLL CLOCK DRIVER TURBOCLOCK™ DESCRIPTION: The IDT5991A is a high fanout PLL based clock driver intended for high performance computing and data-communications applications. A key feature of the programmable skew is the ability of outputs to lead or lag the REF input signal. The IDT5991A has eight programmable skew outputs in four banks of 2 ...

... IDT5991A PROGRAMMABLE SKEW PLL CLOCK DRIVER TURBOCLOCK EXTERNAL FEEDBACK By providing external feedback, the IDT5991A gives users flexibility with regard to skew adjustment. The FB signal is compared with the input REF signal at the phase detector in order to drive the VCO. Phase differences cause the VCO of the PLL to adjust upwards or downwards accordingly ...
