I am RF engineer working on frequency synthesizers.
My request is about the HMC698LP5.
In the application circuit shown in its datasheet (at the end of the document) http://
- How the Voltage (7 V for HMC529) for 13 GHz locked frequency is set?
No external voltage is applied. It is the HMC698LP5 auto lock function?
Using the example 13 GHz:
The reference frequency (100 MHz) is fixed. Then we set the N and S bits for 13
GHz, we apply Vcc and the HMC698LP5 locks itself? Is this the procedure?
If this is the case, could you explain how N and S have been calculated?
(S1, N4 and N5 bits in on state).
Many thanks for your help,
