Hello mates,
Can anyone help me find this transmitter datasheet? I want to check if i can change the 433mhz modulation from FSK to ASK.
Its from a PSA key fob, my 2011+, as the previous cars uses ASK like mine 307.

The markings don't seem helpful. If you can get the FCC ID (probably printed on the case), and look that up, the documents might be somewhat enlightening.
It's probably a purpose-specific chip without public data, though.
