MediaLB Signal Timing
8.5.12.1.
MediaLB AC Spec Type A
Ground = 0V; Load capacitance = 60pF; MediaLB speed = 256Fs or 512Fs; Fs = 48kHz; all timing
parameters 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).

*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.
