LMK03318: LMK03318 - Rising/falling time failed for HCSL output

Ben Kuo

Part Number: LMK03318

Dear team,

Is there any register setting can slow down rising/falling time?

Slew rate now is too Fast, we want to increasing rising time.

If we cannot change by SW, could we add serial capacitor to increasing rising time?

Regards,

Ben

Ben,

Per this thread, there is not a register to change the rise/fall time of the output.

Adding Rs resistors (33 Ohms) can be done to function as overshoot correction, slowing the rapid rise from output - this could aid somewhat (source: https://www.sitime.com/output-terminations-differential-oscillators).

You may try adding a serial capacitor to see if the result is desirable.

Thanks,

Kadeem
