Part Number: ADC3663
Other Parts Discussed in Thread: DS25BR101, DS25BR150

Hi Team,

ADC3663 is Serial LVDS(VOD=700mVpp, VCM=1.0V) output.
Post device is LVDS(VOD=350mVpp, VCM=1.2V) input.

Is it possible to receive the signal of Serial LVDS at LVDS?
Is there any solution that makes it possible?

Best Regards,

Hi,

Please see a list of our LVDS buffers below. DS25BR101 is a good place to start.

Hi Malik,

Thank you for your reply.
Do you mean that DS25BR101 and some LVDS buffer are able to transform SLVDS(VOD=700mVpp, VCM=1.0V) signal to LVDS(VOD=350mVpp, VCM=1.2V) signal?

Correct, You can refer to the datasheet for the specific device that may fit your needs to understand its input and output specs.

Hi Malik,
Thank you for your reply.

I'm looking for a buffer to convert the SLVDS output of the ADC36632 (2CH) to LVDS, as in the attached signal chain.
I consider DS25BR150(1CH x2), however, if you have any recommended device, let me know.

<Other request spec>
Low current consumption
Low noise
Small space

DS25BR150 is my recommendation here but if there is any spec you are concerned about please let me know.
