Receiver Switching Characteristics
Over recommended operating supply and temperature ranges unless otherwise specified
Note 7: 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.
RSKM ≥ cable skew (type, length) + source clock jitter (cycle to cycle)
