Over recommended operating supply and temperature ranges unless otherwise specified.
Note 1: The I
Note 2: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for device operation.
Note 3: Typical values are given for V
Note 4: Current into device pins is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to ground unless otherwise
specified (except V
Note 5: CLHT and CHLT are measurements of the receiver data outputs low-to-high and high-to-low time over the recommended frequency range. The limits
are based on bench characterization and Guaranteed By Design (GBD) using statistical analysis.
Note 6: Receiver Skew Margin with Deskew (RSKMD) is defined as the valid data sampling region at the receiver inputs. The DESKEW function will constrain
the receiver’s sampling strobes to the middle half of the LVDS bit and removes (adjusts for) fixed interconnect skew. This margin (RSKMD) allows for inter-symbol
interference (dependent on type/length of cable), Transmitter Pulse Position (TPPOS) variance, and LVDS clock jitter (TJCC).
