Hello Experts,
Would you tell a turned off sequence of power supply, please? There are some turned on sequence of power supply on E2E, but I don't find turned off sequence. Is there any recommended sequence?
Best Regards,
Fujiwara
Hi Fujiwara-san and Tahara-san,
The device is very flexible to power down sequencing. To best avoid pops/clicks on power down, you should MUTE and power down the output drivers before removing power supplies from the device.
Section 3.1 in the application reference guide gives the timing requirements for RESET. MCLK, BCLK, and WCLK have no requirement for stop timing except that the output drivers should be powered down and muted before clocks are stopped.
Best regards,
