Ground = 0.0 V; load capacitance = 40 pF; MediaLB speed = 1024 Fs; Fs = 48 kHz; all timing

parameters specified from the valid voltage threshold as listed in Table 76; unless otherwise noted.

Table 77 lists the MediaLB 6-pin interface timing characteristics, and Figure 83 shows the MLB 6-pin

delay, setup, and hold times.

1 The controller can shut off MLB_CLK to place MediaLB in a low-power state. Depending on the time the clock is shut off, a runt

pulse can occur on MLB_CLK.

2 MLB_CLK low/high time includes the pulse width variation.

3 The MediaLB driver can release the MLB_DATA/MLB_SIG line as soon as MLB_CLK is low; however, the logic state of the

final driven bit on the line must remain on the bus for tmdzh. Therefore, coupling must be minimized while meeting the maximum

load capacitance listed.
