MCLK
Power-Up Sequence
Reliable power-up can be accomplished by keeping the device in reset until the power supplies, clocks and
configuration pins are stable. It is also recommended that reset be enabled if the analog or digital supplies
drop below the minimum specified operating voltages to prevent power glitch related issues.
The internal reference voltage must be stable for the device to produce valid data. Therefore, there is a de-
lay between the release of reset and the generation of valid output due to the finite output impedance of
FILT+ and the presence of the external capacitance.
Master Mode
In Master Mode, LRCK and SCLK operate as outputs. The left/right and serial clocks are internally derived
from the master clock with the left/right clock equal to Fs and the serial clock equal to 64x Fs, as shown
in
