LMX2594EVM: manual pin ramping

Part Number: LMX2594EVM
Other Parts Discussed in Thread: LMX2594

Tool/software:

Hello.

I want to see the result of Figure 28 (manual pin ramping example) of lmx2594 datasheet.

On the TICS Pro GUI,

I set the configurations as following.

And then,

when I click the 'Clock Ramp' button,

the peak move from 2.4GHz to 2.4035 GHz.

When I click the 'Clock Ramp' button again,

the peak stay on 2.4035 GHz.

But when I click the 'Clock Ramp' button once again,

the peak move from 2.4035 GHz to 2.407 GHz.

And, from this point, whenever I click the 'Clock Ramp' button,

the peak move from 2.407 GHz to 2.4035 GHz,

or from 2.4035 GHz to 2.407 GHz.

Summery,

2.4 => 2.4035 => 2.4035 <=> 2.407

What is the problem?

I want to see

2.4 => 2.4025 => 2.405 => 2.4075 => 2.41 => ...

Thank you.
