SN65LVDT33: How long of a 50 ohm coax cable can this part drive?

Part Number: SN65LVDT33

I have a design that needs to drive the output of the SN65LVDT33 over a 50 ohm coax cable. What are the length limitations?

Hi Katrina,

Max distance is a system dependent parameter depending on many factors (speed, tolerable signal distortion, tolerable jitter, etc.). You will need to test this in your system. There is an EVM for this device that you can use for the evaluation as well.

Currently, we are using the SN74LVC3G17DCUR to drive these cables with success--as a best educated guess, do you think the SN65LVDT33 part is as capable of an output drive as the SN74 part?

Hi Katrina,

No, the SN65LVDT33 does not have as much drive as the SN74 part. I don't have a best guess for the length here as the output isn't meant for driving long distances. That is what the LVDS input is for. Can you put the SN65LVDT33 at the end of your signal?
