DS10BR150

I have a question about output rise time and fall time of DS10BR150.
How much parasitic capacitance on evaluation board outputs did you consider in test condition of DS10BR150?

Best regards,
Y. Hirata

    Hi,

    The DS10BR150 output rise/fall time was tested using a 100 Ohm environment.  The only capacitance attached as an output load was associated with the transmission line itself.  The driver sees the 100 Ohm impedance due to the distributed capacitance and inductance.

    Adding discrete capacitance (like a 0402 size SMT capacitor) would lower the overall bandwidth of the load and slow down the DS10BR150 edge rate if it is placed close to the device output.

    Regards,
