why could I not use a Rset value of <2.7KOhms on the ADISIMPLL simulation tool using ADF4153 chip?
the datasheet specifies Rset range is from 1.5Kohms to 10Kohm.
This is a mistake in the library file.
Take the attached zip file and unzip ADF4153.lib to a temporary location.
Open ADIsimPLL and run a design. From the menu on the main screen choose Libraries / Add Chip Library Update and when asked, point ADIsimPLL to the ADF4153.lib you extracted.
The lower limit should now be 1.5k.
fixed it. thank you!
