(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) For soldering specifications: see product folder at www.ti.com and SNOA549.
(3) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and specifications.

(1) Supply noise testing was done with minimum capacitors (as shown on Figure 49 and Figure 48) on the PCB. A sinusoidal signal is AC coupled to the VDDn (1.8-V) supply with amplitude = 25 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
1 MHz. The deserializer on the other hand shows no error when the noise frequency is less than 750 kHz.
