CDCLVD2102: 1.8V LVCMOS input to 2ch LVDS output

Part Number: CDCLVD2102
Other Parts Discussed in Thread: SN65LVDS104

Hello,

My customer is looking for a solution for 1ch 72MHz 1.8V LVCMOS input to 2ch LVDS output buffer.
CDCLVD2102's VIH is a little bit high for 1.8V LVCMOS. Do we have any good solution?

Regards,
Oba

Hi Oba,

The min. VIH is Vth+0.1V while the max. VIH is 2.5V, so there is no issue working with a 1.8V input clock.

Hello,

Thanks for your answer.
I'll check it.

The customer has another idea. He read the below document.
And using SN65LVDS104 with the same way of Figure 4 in this document could be good.

1.8-V LVDS Driver Using an LVDS Buffer

Does this idea work?

Hi Oba,

Yes it will work but I think it is more straight forward if the customer use CDCLVD2102.
