SN65DSI84: 200Ω Differential Termination

Sadanori Kato

Part Number: SN65DSI84

Hi,

Should the pcb trace is routed with controlled differential 200Ω impedance if using SN65DSI84 with the 200Ω differential termination ?

Hi Kato-san,

I believe so. This was also asked here: e2e.ti.com/.../522944

Hi I.K.-san,

Thank you for the information.

I believe that the pcb trace should be routed with controlled differential 200Ω impedance if setting "1" to "CHA_LVDS_TERM" and "CHB_LVDS_TERM" but would like you to confirm just in case.
In addition, would you recommend to use SN65DSI84 with 200ohm differential termination ?

Best regards,
Kato

Hi Kato-san,

Correct. The termination setting depends on the receiver termination on the panel. I would say 100ohm is more common.
