LM98640: LVDS data output deserialization

Hello Caroline,

Thanks for your question. I'm contacting the applications engineer that supports this product.

Thank you for your answer but it seems that my LM98640 frequency range (5 to 25 MHz) doesn't match with the SN65LVDS96 (20 to 68 MHz).

Is there another solution ?

Regards,

Caroline

Hi Costin,

It seems difficult to use DS90CR218A with LM98640 mainly because of the clocks differencies and frequencies.

Instead of a component, I consider using a WaveVision 5 data capture board.

I already used a WaveVision 5 data capture board (REV c 2008).
What are the differencies between WaveVision 5 and WaveVision 5.1 ?
Could you send me a quotation for this board ?

Regards,

Caroline

Hi Caroline,

I'll find out the differences( if any) and let you know.
For much memory do you need?
What LM98640 version are you evaluating? LM98640 or LM98640QML(space)?

Hi Costin,

I'm using the LM98640EVAL customer evaluation board (LM98640EB Customer evaluation board rev 1).
The LM98640 is the COTS version, not the space QML version.

I used a WaveVision 5 data capture board (REV c 2008) to deserialize data and read/write the configuration registers.
This WaveVision 5 doesn't work anymore, I need a new one. Will the new version WaveVision5.1 still work with my LM98640EVAL board ?

Caroline

Hi Caroline,

It is basically same, just minor changes. The software is the same as in the LM98640CVAL product page, you can order the board online.
