(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions.
(2) The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not ensured.
(3) Typical values represent most likely parametric norms at VDD = 3.3V, Ta = +25 degC, and at the Recommended Operation Conditions at the time of product characterization and are not ensured.
(4) Current into device Pins is defined as positive. Current out of a device Pin is defined as negative. Voltages are referenced to ground except VOD, ΔVOD, VTH and VTL which are differential voltages.
(5) When the Serializer output is at TRI-STATE the Deserializer will lose PLL lock. Resynchronization / Relock must occur before data transfer require tPLD
(6) tPLD and tDDLT is the time required by the serializer and deserializer to obtain lock when exiting power-down state with an active clock.
(7) UI – Unit Interval is equivalent to one serialized data bit width (1UI = 1 / (28*CLK) ). The UI scales with clock frequency.
(8) tDPJ is the maximum amount the period is allowed to deviate over many samples.
(9) tDCCJ is the maximum amount of jitter between adjacent clock cycles.
(10) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC coupled to the VDDn (1.8V) supply with amplitude = 100 mVp-p measured at the device VDDn Pins. Bit error rate testing of input to the Ser and output of the Des with 10 meter cable shows no error when the noise frequency on the Ser is less than 750 kHz. The Des on the other hand shows no error when the noise frequency is less than 400 kHz.
(11) Specification is ensured by characterization and is not tested in production.
(12) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications.

Note: When both devices are locked and the scope is triggered from the TX pixel clock, the RX clock is genlocked to the TX pixel clock and does not drift.
