Original question:

LMG1020: Rise time (Tr) higher than expected

LMG1020: LMG1020

Part Number: LMG1020

Tool/software:

Hi Ti Team,

I was planning to build a short-rise time signal using this LMG1020, can I use a crystal that generates a 1MHz  clock to IN+ and IN- to GND and get an output with a shorter rise time of less than 1ns?

    Hi Ajay,

     

    The datasheet lists the rise time at 375ps when under a 100pF load. As mentioned in the question you referred to, the rise time would be impacted by the capacitive load at the output and is unaffected by how the input is driven, so the 1MHz crystal will be fine.

     

    If you have any further questions, please let me know.

    Thank you,

    Vincent Liew
