Hi
Currently I'm designing RF link using CC1000PP module from Chipcon. I set up
modules to Manchester data format and 19,2 kbps data rate. After calibration
I send data from microcontroler to transmitter with preamble and header. On
the receiver side I read data but in DCLK and DIO I have a lot of jitter.
There is little jitter ( not much ) when data is constant 1 or 0 or when
data is 0xAA, 0x55 etc. In data rate below 19,2 kbps I can read data
correctly, but above 19,2 kbps jitter is so big that I can't correctly read
data from the receiver.
Could you tell me what causes jitter in DCLK and DIO signal ?
Best Regards
