ADIsimPLL allows Rset to vary from 1.5K to 30K. As Rset is changed, the loop bandwidth changes. The ADF4169 datasheet specifies the Rset range as 4.59K to 5.61K. In testing, varying Rset outside the specified range appears to vary the loop bandwidth. What is the maximum usable range that Rset can be varied over?
The datasheet also specifies the maximum Icp as 4.8 ma when RSet=5.1K. By lowering Rset, how high can Icp be increased?
