    I was searching for CD4046 on element14 and happened to arrive at 3 different components under the different sublinks Logic and "Clock, Timing and Frequency Management".

    comparing the datasheet of the ICs of the different products under each link, I noticed that the product under Logic is by TI and the other is by Philips

    Reading through I found that VCO section is identical "word for word".
    Does that mean that the same chip but with different market label?

    Not necessarily, but possibly.

    It is not uncommon to find generic sections of a data sheet to be identical copies (including typos) from one product to another. For instance, if you have 20 different chips that all use the same type of VCO (even though the implementations may or may not be the same), why not write one explanation of how the VCO section works and then use it in all 20 data sheets. That it is used by both TI and Philips may reflect a number of things. It could reflect a licensed second-source for a product, but it could also reflect other things.
