Notes:
1. Normal operation in referenceless mode, minimum output swing with de-emphasis disabled
2. VCC_DDO0/1 = 1.2V
3. The swing is default and de-emphasis is on
4. VCC_DDO0/1 = 1.8V
5. DDO0/DDO0 and DDO1/DDO1 set to maximum swing setting, external crystal reference used
6. Consumption per enabled DDO output
7. Refer to Table 4-3 for the exact register settings for each ΔV_DDO output swing listed
8. For two enabled outputs
9. Maximum input voltage level = 1.8V ± 5%
10. Up to a maximum swing of 800mV
