Note 3: “Absolute Maximum Ratings” are the ratings beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device

should be operated at these limits.

Note 7: JIT is the jitter from any input to any one differential LVDS output running at the specified data rate and data pattern, the other channel is powered off. Jitter

is not production tested, but guaranteed through characterization on a sample basis. Random Jitter is measured RMS with a histogram including 1500 histogram

window hits. K28.5 pattern is repeating bit streams of (0011111010 1100000101). This deterministic jitter or DJ pattern is measured to a histogram mean with a

sample size of 350 hits. Total Jitter is measured peak to peak with a histogram including 3500 window hits.
