Transmitter Switching Characteristics
Note 5: This limit based on bench characterization.
Receiver Switching Characteristics
Note 6: Receiver Skew Margin is defined as the valid data sampling region at the receiver inputs. This margin takes into account for transmitter output skew(TCCS)
and the setup and hold time (internal data sampling window), allowing LVDS cable skew dependent on type/length and source clock(TxCLK IN) jitter.
