(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications.
(3) For soldering specifications, see Absolute Maximum Ratings for Soldering (SNOA549).

(1) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC-coupled to the VDDn (1.8 V) supply with amplitude = 100 mVp-p measured at the device VDDn pins. Bit error rate testing of input to the serializer and output of the deserializer with 10 meter cable shows no error when the noise frequency on the serializer is less than 750 kHz. The deserializer, on the other hand, shows no error when the noise frequency is less than 400 kHz.

(1) Specification is verified by characterization and is not tested in production.
(2) tPLD and tDDLT is the time required by the serializer and deserializer to obtain lock when exiting power-down state with an active RXCLKIN.
(3) When the serializer output is at TRI-STATE, the deserializer loses PLL lock. Resynchronization and Re-lock must occur before data transfer require tPLD.
(4) UI: Unit Interval is equivalent to one serialized data bit width (1 UI = 1 / [28 × CLK]). The UI scales with clock frequency.
(5) Specification is verified by design and is not tested in production.
