Part Number: SN65MLVD204B
Other Parts Discussed in Thread: SN65MLVD206B

Dear Technical Support Team,

Could you provide ibis model for SN65MLVD204B and SN65MLVD206B?

I couldn't find them on their website.

Hi,

Attached are the IBIS models.

mlvd204a.ibs

mlvd206.ibs

Hi Dennis,

Than you for your reply.

I use your attached files instead of SN65MLVD204B and SN65MLVD206B.
I guess that mlvd204a.ibs and mlvd206.ibs show good results on IBIS simulation,
SN65MLVD204B and SN65MLVD206B must be better than them for Signal Integrity.

Hi Dennis,

Thank you for your reply.

mlvd206.ibs includes that c_comp(typ) is 1pF for Receiver Input Model.
Is it appropriate value?

mlvd204a.ibs includes that c_comp(typ) is 3.54pF for Receiver Input Model.

I guess the reason why data rate for 206 is 200Mbps and 204 is 100Mbps.
So lower capacitance is better for improving waveform , especially with many node, right?

Questions of background is following post.

If devices are 204B and 206B, please use mlvd206.ibs. It has the lower input capacitance.

The SN65MLVD20xB have enhancements over similar devices. Improved features include a controlled slew rate on the driver output to help minimize reflections from unterminated stubs, resulting in better signal integrity. The same footprint definition was maintained, allowing for an easy dropin replacement for a system performance upgrade.
