Guaranteed by design and characterization, not 100% tested in production.
Guaranteed by design and characterization, not 100% tested in production.
All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REFOUT is at 14.31818MHz
Slew rate measured through Vswing centered around differential zero
Vxabs is defined as the voltage where CLK = CLK#
Only applies to the differential rising edge (CLK rising and CLK# falling)
Defined as the total variation of all crossing voltages of CLK rising and CLK# falling. Matching applies to rising edge rate of CLK and
All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REF is at 14.31818MHz
Operation under these conditions is neither implied, nor guaranteed.
