TLC2933A: Is There a way to reverse the function of FIN-A and FIN-B?

Taiki Murakami

Part Number: TLC2933A

Tool/software:

Hello everyone!

TLC2933A has PFD, and 4pin(FIN-A) is used as reference input, 5pin(FIN-B) is used as VCO input.

My boss said that there is a way to reverse the function of FIN-A and FIN-B, or FIN-A is used as VCO input, FIN-B is used as reference input.

My boss doesn't know how to achieve this.That's not mentioned in the datasheet.

But My department  product has such circuits, and behaves in that way.

Do you know about this way?

Regards,

Taiki
