Test Conditions/Comments
Internal VCO; direct-to-LVPECL output and for
loop bandwidths < 1 kHz
Test Conditions/Comments
Application example based on a typical
setup where the reference source is
jittery, so a narrower PLL loop bandwidth
is used; reference = 19.44 MHz; R DIV = 162
Integration BW = 12 kHz to 20 MHz
Integration BW = 12 kHz to 20 MHz
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 DIV = 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
