DS90UH948-Q1: Question for power up sequence

Part Number: DS90UH948-Q1

Hi team,

Can you please reply below questions?

The updated datasheet of DS90UH948 shows ">0.2ms" for power supply ramp up time as below table.

Model

revison version

power supply ramp up time

ds90ub926

revison.d(2017.8)

<1.5ms

ds90uh928

revison.c(2016.6)

0.05~1.5ms

ds90uh948

revison.a(2016.1)

<1.5ms

revison.b(2018.11)

>0.2ms

1. I'd like to double check tha it's okay even if the ramp up time will be more than 1.5ms. Is that right?

2. DS90UB926/DS90UH928 datasheets show "<1.5ms". The datasheets will be changed later like as the DS90UH948's modification? Otherwise, the D90UB926/DS90UH928 will not be changed for the ramp up time?

Thanks,

Sam Lee
