Note:
1. For input swing < 720mVppd, the overall cable reach may be reduced.
2. See Table 4-2 for all the output swing settings.
3. For -40°C to -20°C operation at less than 40m of Belden 1694A cable, add 0.1UI to jitter specification.
4. For -40°C to -20°C operation at greater than 40m of Belden 1694A cable, jitter specification does not change.
5. Operation from +70°C to +85°C is not supported.
6. Using Semtechâs recommended application circuit and design guides.
