= 3.0V to 3.6V, serial data rate = 2.75Gbps, T
A
= 0°C to +85°C. Typical values at V
CC
= 3.3V, T
A
= +25°C, unless otherwise
noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 2: Tested using a repeating 1010 pattern at 500Mbps.
Note 3: AC specifications are guaranteed by design and characterization.
Note 4: Deterministic jitter is measured with a repeating K28.5 pattern.
Note 5: With the peak-to-peak input swing on the selected (transmitted) CML input equal to or greater than that on the nonselected
inputs.
Note 6: AC specifications are guaranteed by test.
