HI Mukuno-san,

I will check the charaterization report if this was tested.

Hi Nukuno-san,

I have checked our archives and there was no spread spectrum tolerance tested.

If the datasheet does not have a specification, then I would not recommend applying spread spectrum.

Additional comment.

DS90C385A(Tx) has the spec of SSC.

(From DS90C385A Datasheet)

> Support Spread Spectrum Clocking up to 100kHz Frequency Modulation and Deviations　of ±2.5% Center Spread or -5% Down Spread

Could you please recheck this?

DS90CF386 cannot accept applying SSC. But, DS90C385 can accept SSC.(?)

Hi Mukuno-san,

We do not have any SSC tolerance data for the DS90CF386 at this time.

What is the volume opportunity?
