Part Number: DS90UB925Q-Q1

Hello,

According to following web page, Total throughput of DS90UB925 is 2550 Mbps.

www.tij.co.jp/.../ds90ub925q-q1

I guess total throughput of DS90UB925 is 2975 (85MHz*35Bit/pclk) Mbps.
Does it typo?

Hi, Palaniappan-san

Thank you for your reply. I'm waiting for feedback.

I only wrote DS90UB925 throughput at above thread.
But please confirm throughput of DS90UB92x series.

Hello,

For the DS90UB925 and 927 family the actual line rate is 2975 Mbps, however there is some overhad in framing for scrambling, DC balance, etc, which gives payload rate of 2.635 Gbps. It does seem this value from the comparison chart could be updated.
Apologies for the delay in response as I was away from office several days.

Hi, Liam-san

Thank you for your feedback.

I have one more question.

According to following DS90UB947 web page, Total throughput of DS90UB947 is 5950 Mbps.

This data is the actual line rate of DS90UB947.

DS90UB947 web page is displayed the actual line rate.

DS90UB925 web page is displayed the payload rate.

So, it is different from the display of DS90UB925 web page.

Which one is correct?

Nao

Yes, this is not consistent. I will request for this to be updated by web team.
