Case 1: LMX2592RHAT set to 9750MHz: frequency drifts to 9750MHz + 15MHz after1 second when programmed using the MSP430FR5969IRGZR microcontroller; when using the USBANY programmer (MSP430FR5969IRGZR in reset mode (tristated) everything works fine.
Case 2: LMX2592RHAT set to 8490MHz: frequency drifts to 8490MHz + 11MHz after1 second when programmed using the MSP430FR5969IRGZR microcontroller; when using the USBANY programmer (MSP430FR5969IRGZR in reset mode (tristated) everything works fine.
Note: circuit topology exactly the eval board except the loop filters.
Thanks for your support,
