Part Number: LMK61A2-156M
Do we have 75MHz OSC for output LVDS level with spread spectrum?
You can probably use a clock generator instead. There're CDCE913 and CDCE6214. Both of them support LVDS with SSC.

In reply to Hao Z:
We try to use CDCE6214-Q1.
Could you let me know if this device use both LVDS CLK and SSC?
I couldn't find related setting in datasheet.
In reply to Roy Chou1:
Yes it supports both LVDS output and SSC.
Could you let us know the content in datasheet, I only find SSC in PCIe part.
Please see below:
Maybe I misunderstood. Please note that you'll need to program the part through I2C in order to get LVDS outputs with SSC.
1. My customer would like to operate in LVDS clk = 75MHz. Do I need connect the crystal on PRIREF or SECREF? If I need, how could I choose the value?
2. Could I set VDD_REF / VDD_VCO / VDDO_12 / VDDO_34 = 3.3V? (LVDS = 75MHz which has SSC)
SECREF is the input for crystal. A regular 25MHz crystal will work. And yes you can set all VDD pins to 3.3V.
