SN65LVDS301/302 - Does the device support SSC (spread spectrum clocking) ?

Hello,
I am working with Design to get your answers shortly.

Hello,
I've received confirmation that the LVDS301 is able to pass-through the SSC, we don't have the modulation factor but if Customer tell us their max modulation frequency and factor, we can help to assess it.

Hello Elias-san,

Thank you for your reply and your help. I will ask customer their considering SSC modulation frequency and factor information.

Hello Elias-san,

My apologies for my delay. Our customer will use CDCE913 for their reference clock. Actual connection would be something like below.

CDCE913-------------------->FPGA-------------------->SN65LVDS301
               (10MHz with SSC)             (SSC Clock)

If FPGA internal PLL has transparent characteristic, I believe modulation frequency would depend on CDCE913 SSC function. Regarding the below posts, there is a graph and calculator for modulation frequency of CDCE913 depending on VCO frequencies.

e2e.ti.com/.../1414155

e2e.ti.com/.../303325

If IN/OUT clock is 10MHz, I believe CDCE913 VCO frequency would be 100MHz which modulation frequency is 31.25kHz.

SSC modulation factor is maximum +/- 2%.

Modulation Shape is Triangular.

Finally my question, can we use this SSC for SN65LVDS301/302 PCLK ?

Hi Team,

Could anybody help us support SN65LVDS301/302 using CDCE913 SSC ?
