PLLATINUMSIM-SW: Schematic of Active Filter

Part Number: PLLATINUMSIM-SW

Tool/software:

Hi TI team.

I'm designing a loop filter using PLLATINUM SIM and considering a 3rd Order filter with an Active Type C.
The schematic displayed in PLLATINUM SIM seems to show the op-amp output as shorted. (Figure.1)
On the other hand, the User Guide presents a different schematic (Figure.2).
Which one is the correct diagram?

Figure.1

Figure.2

Hi Matsumoto-san,

Both Figure 1 and Figure 2 are identical and correct.

Here is a bigger picture, FYI.

Thank you for your response.

I noticed a discrepancy between the image you provided and the display on PLLATINUMSIM,
particularly around the area marked in red.
Just to confirm, we're going with the information you've sent, correct?
