LMH1983: convert to LVTTL from LVDS

Yasushi Fujiwara

Part Number: LMH1983
Other Parts Discussed in Thread: SN65LVELT23

Hi Experts,

My customer would like to convert to LVTTL for LMH1983 output. Customer would like to use SN65LVELT23, then customer has question.
1. It can connect directly between LMH1983 output and SN65LVELT23 input(Dx), correct?
2. If above is correct, termination(100ohm) is needed?

Best Regards,
Fujiwara

Hello,

Yes, in order for the LMH1983 to have LVDS level swing it needs to have the termination provided on the datasheet (100 ohm). Then you can connect the output of the LMH1983 to the LVTTL converter.

Thanks and regards,

Amin
