RE: Clause 51 (XSBI) LVDS spec


If there is a deviation that we want to allow, we will need to specify 
it. Common mode output voltage tolerance shouldn't be an issue if we
agree that the interface is AC coupled. Were there other problems?

Justin Chang:
The IEEE 1596.3 LVDS spec has a few parameter specifications that very
many LVDS circuits do not follow in detail, e.g. the unloaded common mode
output voltage tolerance of 1200mV +/-75mV. 

Can the electrical specs in clause 51 referring to  IEEE 1596.3 be assumed
also inherit the generally accepted deviations?
