UCC2895: Oscillator frequency total dispersion

Part Number: UCC2895

Hi,

I am using the UCC2895DW from Texas Instruments in a design.

I have questions about the oscillator frequency  dispersion given in the datasheet.

In the datasheet page 4, for oscillator frequency dispersion, do we have to consider «+/- 5.4%@ 25°C »  and « +/-5% over line temperature range »?

( for information, +/-5.4% @25°C is obtained by calculating  +/- 27kHz variation @500kHz )

Or do « Frequency total variation » includes dispersions @25°C?

Another point, there are also dispersions given such as VCT(peak) , VCT(valley) and VRT which influence the oscillator frequency as shown on page 8 of the datasheet (See graph below):

Does the « +/-5.4% dispersion given @25°C » + « 5% dispersion over line,  temperature range » include the VRT, VCT(peak) and VCT(valley) dispersions ?

Or do " VRT, VCT(peak) and VCT(valley) "  have to be added to the total oscillator frequency dispersion?

Thank you in advance.

Yves.
