MB86R02 ‘Jade-D’ Hardware Manual V1.64
*1: 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 minimized while meeting the maximum
capacitive load listed.
34.5.14.2
MediaLB AC Spec Type B
Ground = 0V, Load capacitance = 40pF, MediaLB speed = 1024Fs, and Fs = 48kHz.
All timing parameters are specified from the valid voltage threshold as listed below; unless
otherwise noted.

*1: The controller can shut off MLBCLK to place MediaLB in a low-power state.
*2: Pulse width variation is measured at 1.25V by triggering on one edge of MLBCLK and measuring the spread on
the other edge, measured in ns peak-to-peak (pp).
