Test Conditions/Comments
Application example based on a typical
setup where the reference source is
clean, so a wider PLL loop bandwidth
is used; reference = 15.36 MHz; R = 1
Integration BW = 200 kHz to 10 MHz
Integration BW = 12 kHz to 20 MHz
Integration BW = 200 kHz to 10 MHz
Integration BW = 12 kHz to 20 MHz
Integration BW = 200 kHz to 10 MHz
Integration BW = 12 kHz to 20 MHz
