Hello,
VCC_CP is VCC of VC(X)O. When Charge Pump Preset to VCC_CP/2 is used, CP output will be VCC_CP x 0.5 voltage.
[Questions]
- What is the voltage tolerance of CP voltage when Charge Pump Preset to VCC_CP/2 used? I guess this voltage doesn't trim for more voltage accuracy.
- How to generate this voltage internally? Resister divider from VCC_CP to GND or any other way?
[VC(X)O question]
- VC(X)O is voltage control oscillator. When VCC of VC(X)O is different but control voltage is mid of VCC, VC(X)O frequency is usually same or different?
Best regards,
Toshihiro Watanabe
