Chip identification. OM9663?

[Aroni525]

Dear all,

I have recently got a development PCB with a mysterious NXP NFC frontend chip that I have to code.

The only information I have found based on the chip marking are from some chinese websites. They say the part number is OM9663. Unfortunately I cannot find anything like this on the official NXP website.

Any clue which NXP chip is this?:

And a more detailed datasheet

Came along this chip too, not sure why it apparently completely vanished from the NXP website.

It's a 13.56 MHz RFID Reader IC.

I attached the public datasheet.
