Other Parts Discussed in Thread: USB2ANY, LMX2594
Greetings sir,
We are making use of LMX2595 in our project for frequency application in range of 15 - 18 GHz. For phase synchronization purpose, according to figure 33 of data sheet our application falls in category 3 since we make use of fractional mode, with fOUT % fOSC != 0 (please confirm).
When we tried to program EVM with Phase Sync option, PLL did not get locked for frequencies above 15 GHz. However, for similar settings it locks for frequencies less than 15 GHz. I have attached the GUI settings we used, for reference 6813.15.555GHz-SYNC-e2e.tcs . Please tell us the appropriate method/steps to program PLL for frequencies above 15 GHz (particularly 15805 MHz) with phase sync option for category 3 application.
Also, we wished to confirm whether the SYNC pin in EVM needs to be externally triggered or USB2ANY board has provision for the same.
Regards,
Karan
