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).
Gate delays due to OR'ing logic on the pins must be accounted for.
When a node is not driving valid data onto the bus, the MLBSO and MLBDO output lines shall remain low. If the output lines can float at anytime, including while in reset,

external pull-down resistors are required to keep the outputs from corrupting the MediaLB signal lines when not being driven.
