Typical Example
Multiple Output Example
40 MHz
VDD
The following connection diagram shows the implementation of the example from the previous section.
This will generate a 50 MHz clock synchronously with a 40 MHz input. A SYNC pulse is desired and the 1x
output drive is selected.T
Note: The series termination resistor is located before the feedback trace.
This will give the following waveforms:
In this example, an input clock of 125 MHz is used. Eight copies of 50 MHz are required as are eight copies
of 25 MHz, de-skewed and aligned to the 125 MHz input clock. The following solution uses the
MK74CB218 which has dual 1 to 8 buffers with low pin-to-pin skew.
