I have one question about ADV7441A power supply sequencing. On specification "ADV7441A_HW_REVJ.pdf", page 317 there is a graphics of supplies timings. However, there is not a clear specification about delay between 1.8V and 3.3V, rise time, fall time. Is there any other information about it?
Checking reference board schematic, I have seen that there is not sequencing on supplies power up. Just linear regulators which starts all together. Is it really required to do an special power up sequence? My application is required for external uses and I must avoid any latch durin devices power up/down. Can somebody tell me the timings for figure 114 and 115 of specification?
Thanks for your support,
