DP83867IS: Inquiry about functional difference

Cedrick
Expert 8270 points
Part Number: DP83867IS

Hi,

Good day.

Our customer would like to know the difference between the DP83867CSRGZ, DP83867ERGZ and DP83867ISRGZ. Other than the operating temp, are there any other functional difference?

They noticed that there is one specification Start of Frame Detection Timing on page 13 which is different for E and IS/CS version. Please confirm, how important the parameter for function of the chip. Please also confirm, if there is any other functional difference among the three versions.

Will it work as it is without any hardware / software change if We replace one part with the other?   

Thank you


Regards,

Cedrick

    Hello Cedrick, 

    Thank you for the query.

    Please see below 

    Key is the temperature and these devices should be interchangeable.

    Regarding the variation of the specs on page13, the parameters should not have any effect on the communication performance as this is used for IEEE1588 time stamping.
