Note 11: tOSHL/tOSLH and tOST - Output to output skew is defined as the absolute value of the difference between the actual propagation delay for all outputs
within the same packaged device. The specifications are given for specific worst case VCC and temperature and apply to any outputs switching in the same
direction either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH) or in opposite directions both HL and LH (tOST). This parameter is guaranteed by design and
statistical process distribution. Actual skew values between the GTLP outputs could vary on the backplane due to the loading and impedance seen by the
device.
Note 12: tPV - Part to part skew is defined as the absolute value of the difference between the actual propagation delay for all outputs from device to device.
The parameter is specified for a specific worst case VCC and temperature. This parameter is guaranteed by design and statistical process distribution. Actual
skew values between the GTLP outputs could vary on the backplane due to the loading and impedance seen by the device.
Note 13: Due to the open drain structure on GTLP outputs tOST and tPV(LH) in the A-to-B direction are not specified. Skew on these paths is dependent on the
VTT and RT values on the backplane.
Note 14: tPDELLH and tPDELHL -B to CLKOUT propagation delay delta is defined as the difference between the CLKAB to CLKOUT propagation delay and the
CLKAB to B propagation delays. This parameter is for a given device and is not meant to guarantee the delta between the CLKAB to CLKOUT propagation
delays of one device and the CLKAB to B propagation delays of other devices. This parameter is guaranteed by design and statistical process distribution.
