CC1101: Access TX Framed Output

The received preamble and sync word are not stored. For debug you can set the sync word equal to 0xAAAA and use fixed length payload to see if you receive the expected packet. 

Thanks, but I am trying to access the framed bits that are generated in the transmitter on the transmit side. 

Could you elaborate some on why you want to do this? It sounds like you want to debug something and it could be possible to find other ways to solve your issue. 

We are building a custom 100 GHz FSK transceiver using the CC1101 initially.  For the transmit side, the synthesizer chip we are using (ADF4159) has a pin to directly FSK modulate the LO.  Currently I am emulating the CC1101 packet generation (preamble + syncword + encoded bits) in microcontroller and driving the synthesizer TX pin with the micro controller.  This works, but is limited to a low data rate.  

Due to SWAP requirements we cannot do a multistage upconversion to upconvert the FSK modulated CC1101 output.

I was looking for a way, if possible, to get access to the TX packet bits of CC1101 and drive a GDO pin with them to drive the TX pin on synthesizer.

Thanks,

Jeff
