AMC1303M0510: Time from DVDD rise to CLKOUT start

Hi,

What is the time from DVDD startup to CLKOUT start?
There is no problem if it is not a guaranteed value.

Hello Sakai-san,

Unfortunately this is not specified, however I would expect the clock output to begin shortly after DVDD powers up as shown in the figure.

Hi,

Our customers want to know the waiting time when inputting CLK to MCU.
How much waiting time should they prepare from the start of DVDD?

Hi Sakai-san,

This is going to depend on how quickly DVDD ramps up in their system.

For example, If I set my power supply to current limit at 1A, I see the clock begin to output when DVDD is around 2.7V. If I set my power supply to current limit at 200mA such that DVDD ramps up slower, I see the clock begin to output when DVDD is around 2.3V.

Hi,

I understand the start of DVDD.
What is the time from the start of DVDD to the start of CLKOUT?
Could you tell me the reference timing?

Best regards,

Hi Sakai-san,

As I said in my last email, the timing from the start of DVDD to the start of CLKOUT will be dependent on how quickly DVDD ramps in the customer system.
