... LOW SKEW CLOCK BUFFER Description The ICS621 is a low skew, single input to four output, clock buffer. The device operates from a single 1.2 to 1.8 volt supply and has a 3.3 volt tolerant input, making it ideal for level translation. IDT makes many non-PLL and PLL based low skew output devices as well as Zero Delay Buffers to synchronize clocks ...

... To achieve the low output skew that the ICS621 is capable of, careful attention must be paid to board layout. Essentially, all four outputs must have identical terminations, identical loads and identical trace geometries. If they do not, the output skew will be degraded. For example, using a 30 Ω ...

... LOW SKEW CLOCK BUFFER Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the ICS621. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. ...
