15.9
Since the LP-Serial electrical specification are guided by the XAUI electrical interface specified in Clause
47 of IEEE 802.3ae-2002, the measurement and test requirements defined here are similarly guided by
Clause 47. In addition, the CJPAT test pattern defined in Annex 48A of IEEE 802.3ae-2002 is specified as
the test pattern for use in eye pattern and jitter measurements. Annex 48B of IEEE 802.3ae-2002 is
recommended as a reference for additional information on jitter test methods.
15.9.1
For the purpose of eye template measurements, the effects of a single-pole high pass filter with a 3 dB point
at (Baud Frequency)/1667 is applied to the jitter. The data pattern for template measurements is the
