A positive number indicates that CLKOUT precedes CLKIN, A negative number indicates that CLKOUT follows CLKIN.
Skews are measured in clock mode 29, with a CLKIN:CLKOUT ratio of 1:1. The same skew is valid for all clock modes.
CLKOUT skews are measured using a load of 10 pF.
CLKOUT skews and phase are not measured for 500/166 Mhz parts because these parts only use CLKIN mode.
