Does the Si5338 I2C slave have a timeout?

Hi,

I am using the Si5338 in one of our applications. Does the I2C slave in this chip have a timeout feature? Specifically, between the time that the slave (Si5338) is addressed and it ACKs it in response to the master, is there a limit on the amount of time the master has to write the register it wants to write? If so, what's the exact timeout? I would appreciate your prompt response.

Thanks,

Alex

any chip that is I²C does not have a timeout.  The I²C spec does not have a max time.

That's strange because I'm observing a ~30 [ms] timeout.

what are you talking to the Si5338 with?. You can talk to any I²C with a SMB device but that will give you timeouts

I see the timeout on the Si5338 bus. Specifically, after there is a 30 ms time delay after it is being addressed and a register read or write.

It's a lot easier to communicate in these fora if posters answer questions

what are you talking to the Si5338 with?.
