xe 1203 problem with the bit-sync

[wolf69]

xe1203

Anyone used this RF chip?
I'm experimenting problems without barker coding.
the b it-sync is not working well: receiving two ones (or zeros) sometimes rx-clock speeds up generating three riseing up clock edges :? . Disableing the bit -sync results in getting perfect data but without clock! so uC should auto-syncronizes...
With barker code data tx-rx works well but FEI (frequency error index) looks unavaliable.

Anyone can help?

Thank you

hi wolf

have you already tried to get in touch with Xemics? perhaps they can help you (but honestly, i'm not too sure about it).
we are using acutally the 1202 and we didn't encounter any problems so far (whereas the 1201a was buggy)
