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.
