TCAN1042V-Q1: Total loop delay

Daniel Wang (auto)

Part Number: TCAN1042V-Q1

Tool/software:

Hi team,

Greeting for the day!

As shown below, the test result of t_PROP(LOOP2) is 171ns, which is nearly to the maximum value in datasheet of 175ns, so is it necessary to modify? and how to improve?

Thanks!

    Hi Daniel,

    Thank you for your question sharing the oscilloscope results. The good news is that your measurement falls within the expected guaranteed range for the device. Oftentimes this measurement is likely related to your test setup. Was the device run in normal mode using a load resistor of 60 ohm, a load capacitor of 100 pF and CL(RXD) of 15 pF used in the setup? These were the test conditions used during characterization to capture the tprop loop 1 and loop 2 switching characteristics range. 

    Regards, Amy
