UCC2801: UCC2801 data sheet

Part Number: UCC2801

Tool/software:

UCC2801 data sheet, Document SLUS270G – MARCH 1999 – REVISED MAY 2020, Figure 9-6. Oscillator Equivalent Circuit shows 2.65V reference voltage.

UCC2801 data sheet, Document SGLS135F − SEPTEMBER 2002 − REVISED OCTOBER 2010, Figure 1 shows 2.5V  reference voltage.

1. Is UCC2801-EP different than UCC2801?

2. If yes, are there any other differences?

3. If no, which value is correct and what is the impact on the output frequency [%] due to the reference voltage difference?

Thank you.
