Since GMSL1 supply noise rails are not specified, the GMSL2 noise supply requirements can be applied to GMSL1 devices. The frequency of the supply noise should also be less than 1MHz.
| Rail | Voltage | Typical Supply Noise |
|---|---|---|
| VDD18 | 1.8V | 25mVpp (1.4% ripple) |
| VDD | 1.0V | 25mVpp (2.5% ripple) |
| 1.2V | 50mVpp (4.2% ripple) | |
| 1.3V | 50mVpp (3.8% ripple) | |
| VDDIO | 1.8V | 50mVpp (2.8% ripple) |
| 3.3V | 100mVpp (3% ripple) |
