Hello,

My customer has a question about LMH1297.

[Q]

What are the input conditions that satisfy AJCD_MODE?
(D/S, p13, RECLOCKER OUTPUT JITTER, Alignment Jitter)

Their result is 0.3 ~ 0.4 [UI].

Best Regards,

Kudo-San,

Per SMPTE standard, we should use color bar or a similar pattern like PRBS10 with a 1m long cable to make this measurement. Please check instrument generating this pattern to make sure it meets alignment jitter requirement (less than 0.3UI) by itself. This guarantees the instrument by itself does not have high in-band jitter.
