CC2500: Inquiry about CC2500 jitter deviation width

Jitter here is difficult to specify. See here:  CC2500: CC2500 Bit Synchronization jitter

Could you please provide a numerical value for how many microseconds (±μSec) of jitter might be expected under the given conditions?

It does not have to be an exact value—a rough estimate or value under assumed conditions would be very helpful.

To answer this question I'll need a few assumptions cleared up:

1. Are you using sync or async mode? 

2. Are you putting the signal on the chip'sI/O pin to be parsed by an MCU?

1. Are you using sync or async mode? 

ANS：We are using asynchronous mode.

2. Are you putting the signal on the chip'sI/O pin to be parsed by an MCU?

ANS：Yes, the signal is being output on the chip’s I/O pin to be parsed by an MCU.

After some digging through old documents, the CC2500 and CC1101 have almost identical architecture and design. The datasheet for CC1101 shine on light on the jitter. See below.

"In asynchronous serial mode no data decision is done on-chip and the raw data is put on the data output line in RX. When using asynchronous serial mode make sure the interfacing MCU does proper oversampling and that it can handle the jitter on the data output line. The MCU should tolerate a jitter of ±1/8 of a bit period as the data stream is timediscrete using 8 samples per bit. In asynchronous serial mode there will be glitches of 37 - 38.5 ns duration (1/XOSC) occurring infrequently and with random periods. A simple RC filter can be added to the data output line between CC1101 and the MCU to get rid of the 37 - 38.5 ns ns glitches if considered a problem. The filter 3 dB cut-off frequency needs to be high enough so that the data is not filtered and at the same time low enough to remove the glitch. As an example, for 2.4 kBaud data rate a 1 kohm resistor and 2.7 nF capacitor can be used. This gives a 3 dB cut-off frequency of 59 kHz."

Thank you very much for your response.
Could you also kindly confirm the same points for the synchronous serial mode as well?
Thank you for your continued support.
