ECO configuration

The ECO is disabled by default and needs to be enabled for usage. Also, trimming is necessary to use the ECO.
This device can set the trimming parameters that control the oscillator according to the crystal unit and
ceramic resonator. The method to determine the parameters differs between the crystal unit and ceramic
resonator.
You can configure these parameters in the System tab of the ModusToolbox™ Device Configurator.
ModusToolbox™ software will automatically generate the corresponding code.

Use case

Oscillator to use
Fundamental frequency
Maximum drive level
Equivalent series resistance
Shunt capacitance
Parallel load capacitance
Crystal unit vendor's recommended value of negative resistance
Automatic gain control
Note: These values are decided in consultation with the crystal unit vendor.
You can configure these parameters in the System tab of the Device Configurator; based on these,
ModusToolbox™ software automatically generates the corresponding code.
