Pulse width variation is measured at 1.25 V by triggering on one edge of MLBCLK and measuring the spread on the other edge, measured in nanoseconds peak-to-peak (ns p-p).
The board must be designed to ensure that the high impedance bus does not leave the logic state of the final driven bit for this time period. Therefore, coupling must be
