Hi,recently our customer designing ADF4193 refer to Evaluation Board sch.However the frequency always unlock.
Can you help support relative configure reference code? Thanks.
In the ADF4193 eval board software, there is a setting to lock the PLL into wide bandwidth mode, which was useful for us in debugging some stability issues with an external op-amp. Now that we have the board back, I don't see the register setting that…
I have a quick query regarding the ADF4193 register map. Unlike the ADF4351, the 4193 has registers of a differing number of bits (p.14 of D/S). However, I presume that as you write the control bits last due to the serial programming being MSB first that…
CP has an output voltage of 1.2V~Vp3-0.3V, but after adding an CMR voltage 3V, voltage range becomes 1.8V~Vp3-0.8V. How does this work? I feel confused and when designing circuits that extending VCO tuning voltage. Thank you!
The latest ADF4193 and ADF4196 software (v6) is attached.
1. Disconnect any evaluation board
2. Download and run the attached installer
3. Click Next/Continue/Finish when asked
4. Connect your evaluation board
5. Windows will…
ADIsimPLL models fractional spurs but not integer boundary spurs which are caused by a separate mechanism, namely
interaction between the RF and harmonics of the reference frequency. The ADF4193 datasheet talks about one method to avoid integer boundaries…
Lock time depends on PLL loop bandwidth. Wide loop bandwidths lock quickly. Narrow ones slowly.Download ADIsimPLL to get an estimate of performance.For fast locking applications the ADF4193 is the fastest part we have.
I can provide the source codes for both applications if you want.
