ABSOLUTE MAXIMUM RATINGS

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.

Continuous Output Current (OUT+, OUT-) .......-25mA to +25mA

Operating Ambient Temperature Range ............... 0°C to +85°C

Storage Ambient Temperature Range...............-55°C to +150°C

6-Pin TDFN (derate 24.4mW above +70°C)..................1.95W

Note 3: Difference in deterministic jitter between data source and equalizer output, evaluated at 2.5Gbps, 3.2Gbps, 5Gbps, and

Note 4: Signal is applied differentially at input to a 6-mil wide, loosely coupled stripline. Deterministic jitter at the output of the

transmission line is from media-induced loss, not from clock source modulation (see Figure 1).
