DS90UB925Q-Q1: On the amplitude deviation of spread spectrum

user5917751

Part Number: DS90UB925Q-Q1

I would like to input a clock signal with an amplitude deviation ± 3% to the IC using the spread spectrum function.

So please tell me the followings.

1. Although the amplitude deviation is ± 2.5% according to the specifications of the IC, what percentage of the amplitude deviation can be input as a performance?

2. Is there an IC that is pin compatible with the DS90UB925Q - O1 and can input with even greater amplitude deviation?

Could you clarify on question 1?
2. Unfortunately, we do not have any compatible device with greater SSC tolerance.

I'm sorry.

I will explain Question 1.

1. If the LVDS clock signal is input with the amplitude deviation set to ± 3%, can the IC receive signals normally?

How about the situation about the following questions?

1. If the LVDS clock signal is input with the amplitude deviation set to ± 3%, can the IC receive signals normally?

There's is no guarantee since the SSC is out of spec.
