Other Parts Discussed in Thread: DS92LV2422, DS92LV2412

Hello,

I read the datasheet of the DS92LV2422 and have a question about output data valid times.

It mentioned 0.5UI typical, UI =1/28*CLK.

If this specification is the relation between CLKOUT and DO, UI value is too large.

Does it mean 0.5T ? (T is CLK cycle)

Hi Naoki-san,

Thanks for bringing this to our attention. Yes, you are correct. It should be T.

This is a mistake in the datasheet. If you look at a more updated datasheet for a similar lower-speed version of the deserializer (DS92LV2412), the value is listed correctly for the same graphic:

We will add the correction for the next datasheet revision.

Thanks,

Michael
