What is the PWM output limit?

I haven't powered up or configured anything in the ecu yet, just about done with the wiring portion.  I think I remember reading here somewhere the output limit of the PWM was 500 hz?  I can't recall exactly and wanted to verify to confirm if I needed another crank sensor or not.  My transmission needs to see a 24x/rpm signal, was hoping to output a speed signal from the ecu but I don't think its fast enough.
