DESCRIPTION  
The CDCF5801 provides clock multiplication from a reference clock (REFCLK) signal with the unique capability  
to delay or advance the CLKOUT/CLKOUTB with steps of only 1.3 mUI through a phase aligner. For every rising  
edge on the DLYCTRL pin the CLKOUT is delayed by a 1.3-mUI step size as long as the LEADLAG input  
detects a low signal at the time of the DLYCTRL rising edge. Similarly for every rising edge on the DLYCTRL pin  
the CLKOUT is advanced by a 1.3-mUI step size as long as the LEADLAG pin is high during the transition. This  
unique capability allows the device to phase align (zero delay) between CLKOUT/CLKOUTB and any one other  
CLK in the system by feeding the clocks that need to be aligned to the DLYCTRL and the LEADLAG pins. Also it  
provides the capability to program a fixed delay by providing the proper number of edges on the DLYCTRL pin,  
while strapping the LEADLAG pin to dc high or low. Further possible applications are:  
Aligning the rising edge of the output clock signal to the input clock rising edge  
Avoiding PLL instability in applications that require very long PLL feedback lines  
Isolation of jitter and digital switching noise  
Limitation of jitter in systems with good ppm frequency stability
