Did you look at the layout guideline app note, an1085?
As LVDS drivers, designed for mobile phones, they should be 'quiet'', by
design, but, without some idea of your application, and where you're having
problems, it's difficult for anyone to help out. One suggestion, beyond AE
assistance, is to find a mobile phone that uses this part, check schematic of
the phone for any added resistors or rf filter arrays, maybe do a visual
examination of such a phone....
