LVDS spec problem

Can anyone explain what does H-sink current and L-sink current means? (As stated in Datasheet1 page 2 PHY Electrical Specifications)

Are they different than High level input current and Low level input current? (As stated in Datasheet2 page 6 & 7 )
 

Re: LVDS spec problem

I finally found the answer for the LVDS spec problem. The H-sink and L-sink current means that the transmitter sinks current from receiver.

Datasheet1 and Datasheet2 are different. In Datasheet2 design, the transmitter transmit current to reciever. But in for Datasheet1, the opposite happens. Datasheet1 integrates both LVDS signaling concept with WhisperBus concept.

Worth of looking into the WhisperBus concept.

Anyone can tell what data rate can be achieved by WhisperBus + LVDS?
