"I'm designing a board around the ADSP-21565 with three power rails — 3.3V (ADP7104), 1.8V (AP2112K), and 1.1V (TPS62130A). The 1.8V feeds VDD_REF and VDD_ANA, the 1.1V feeds VDD_INT, and 3.3V feeds VDD_EXT. Does the ADSP-21565 have any hard power sequencing requirements between these rails, and if so, does a passive RC-based sequencing approach satisfy them or is active sequencing required?"

Mark.
Hi, Nandini, and thank you for your reply.
Could you possibly point me to a reference design or application note that shows the recommended active sequencing approach for the ADSP-21565 with 1.1V, 1.8V, and 3.3V rails? Specifically whether a dedicated sequencing IC is recommended or whether a simpler RC and enable pin approach is sufficient.
regards,
Mark.
