Transmitter Switching Characteristics
Over recommended operating supply and temperature ranges unless otherwise specified
Note 5: The Minimum and Maximum Limits are based on statistical analysis of the device performance over process, voltage, and temperature ranges. This
parameter is functionality tested only on Automatic Test Equipment (ATE).
Note 6: The limits are based on bench characterization of the device’s jitter response over the power supply voltage range. Output clock jitter is measured with a
cycle-to-cycle jitter of +/−3ns applied to the input clock signal while data inputs are switching (See Figures 15 and 16). A jitter event of 3ns, represents worse case
jump in the clock edge from most graphics controller VGA chips currently available. This parameter is used when calculating system margin as described in AN-1059.
