Specification is specified by characterization and is not tested in production.
(2)
tSKD1, |tPLHD tPHLD|, Pulse Skew, is the magnitude difference in differential propagation delay time between the positive going edge and
the negative going edge of the same channel.
(3)
tSKD2, Channel to Channel Skew, is the difference in propagation delay (tPLHD or tPHLD) among all output channels in Broadcast mode
(any one input to all outputs).
(4)
tSKD3, Part to Part Skew, is defined as the difference between the minimum and maximum differential propagation delays. This
specification applies to devices at the same VCC and within 5°C of each other within the operating temperature range.
(5)
Measured on a clock edge with a histogram and an accumulation of 1500 histogram hits. Input stimulus jitter is subtracted geometrically.
(6)
Tested with a combination of the 1100000101 (K28.5+ character) and 0011111010 (K28.5- character) patterns. Input stimulus jitter is
subtracted algebraically.
(7)
Measured on an eye diagram with a histogram and an accumulation of 3500 histogram hits. Input stimulus jitter is subtracted.
