Question:
What kind of type of XTAL used for external crystal oscillator (ECO)?
Answer:
Crystal Unit and Ceramic Resonator can be used for ECO. Traveo II has a built-in ECO gain control amplifier and can support various Xtals by setting the amplifier parameters.
Amplifier parameters are calculated using the specifications of Xtal. For more details, see the “Clocking System” section of the Architecture Technical Reference Manual and the ECO User Guide. If the calculation result of an XTAL is out of the specified range, the corresponding Xtal cannot be used.
Note: This KBA applies to the following series of Traveo II MCUs:
- CYT2 Series
- CYT3 Series
- CYT4 Series
