Hi Team,

Please allow me to ask you the specification which could not find in the data sheet.

Our customer needs to know the LVDS serial bit delay time as described in the following figure.

I can find delta TPPOS = +/-0.06UI (Typical), would this be the value ?

If so, could you please tell us the maximum value for this spec ? If there is no data, it would be helpful if you could share us estimated data.

Best Regards,

Kawai

Kawai,

Yes, the 0.06UI would be the bit delay time value. The typical value is what we characterized this specification up to, but I will try and see if I can find some more data on this. Thank you for your patience.

Kawai-san,

Unfortunately, it seems that this parameter was only spec'd for a typical value. I was unable to find any data suggesting what the max value for this parameter may be.

As stated in a previous thread, I am working on getting an EVM to try and measure this spec (as well as the other specs you have requested in other threads) on my own. I will do my best to update you for when I can expect to get some measurement results by.

Regards,
Jonny
