4.1 Base Line Power Consumption

The baseline power consumption number for each mode is measured by setting the following parameters. These numbers serve as a benchmark for observing changes in power consumption with change in parameters.

  • Temperature: 25 °C
  • Channel Utilization: 50%
  • Cable Length: 100m
  • VDDIO: 1.8V
