Hi,

I did not understand the difference between the terminologies CML and rail to rail.Could somebody please help me out.

Regards
 

Re: CML and Rail to rail

CML = Current Mode Logic
Rail to rail: typically to describe the voltage can swing to the highest supply voltage (for example, Vdd) to lowest supply voltage (for example, ground)
 

CML and Rail to rail

CML implies differential and reduced voltage swings. It's one of several high speed differential digital styles/interfaces.

Check out below for more info.

Rail to rail in this context describe your "standard" digital circuit / interfaces - ie. CMOS, in that the signal goes between the power and ground rails.
