Hi
I need to generate ramp (fast ramp) with quite demanding requirements. Due to the ADsim simulation results, I need about 2MHz PLL filter band. With that band, bleed current is must be for single freq with integer mode.
I wonder, if "bleed current' is working during ramp generation and how it impact on the ramp?
The PLL filter may be design with almost the same parameters, but with different CP currents? I wonder, if there are any suggestion, that I should use high or low CP current with my design
I found one application note (AN-1154) about bleed current, but there is no info about ramp generation. Do you have any other papers?
Any suggestions?
