DS96F175MQML-SP: Relative timing delays

Part Number: DS96F175MQML-SP

Tool/software:

I am using an RS485 bus with data and clock at 5 Mbps.

I need to perform a worst-case analysis on the timing, to verify the margin between data and clock.

Do you have any data on the relative timing delays of 2 receivers in the same package?

Or can I assume half the worse-case delay as the difference between receivers, given that they're on the same process and at the same temperature?

Many thanks,

Michael

  • Hi Michael,

    This is probably a safe assumption. Generally the skew between two channels will be minimal when they are on the same die, at the same temperature, with the same process (so process variation wouldn't effect it much). I wouldn't expect a very large skew difference and half of the worse case delay would probably give a lot of margin for you.
