Part Number: LMX2594EVM
Other Parts Discussed in Thread: LMX2594,
I am using lmx2594EVM. I want to generate ramp from 7.5 GHz to 15 GHz using lmx2594. VCO ramp is given in the lmx2594 datasheet, page no.15 figure.11. How to generate this ramping using TICS pro. Please suggest us.

Hi There,
Here is the configuration for the example in datasheet section 7.3.13.2.1. You can modify it according to your need.
Please note, there is a VCO calibration every 50MHz accumulated frequency change and 50µs is reserved for the calibration.
Hi JSK,
The ramp engine operates with the PLL denominator = 2^32 -1. As a result, the end frequency may not be exactly what you want.
In addition, when the VCO frequency is changing, there is always an overshoot due to the loop filter response. For example,
