Dear All,
Please answer our cutomer's inquiry.
Our customer would like to knowabout type of Spread-Spectrum Clock modulation of CDCE949.
ie ) Sawtooth Shape , Hershey Shape , Sinusoidal Shape .
and modulation cycle of SSC.
I believe CDCE949 data sheet shows only description about SSC as below.
--------------------------[ from Data Sheet SCAS844D Page.2 ]
All PLLs support SSC (Spread-Spectrum Clocking). SSC can be Center-Spread or Down-Spread clocking. This is
a common technique to reduce electro-magnetic interference (EMI).
1) Please give us the application Repor about SSC modulation type of the CDCE949,
ike as Application Report SCAA103– of CDCS502/503.

2)Is there any data of modulatiion cycle about frequency change ?
Thank you and best regards. Miyazaki.
