TIDA-00333: Data rate inquiry

Tool/software:

Dear Experts,

I have a question about the TIDA-00333 design. The transceiver used in this design is the ISO3082, which, according to the datasheet, has a data rate of 200 kbps. However, in the TIDA-00333 guideline, it is mentioned that the data rate is limited to 100 kbps.

My question is: Why is the data rate reduced to 100 kbps? My required data rate is 115200 bps. I understand that you recommend ISO1410 for higher data rates, and its data rate is specified as 500 kbps. Based on the new design, what is the actual achievable data rate?

Additionally, I have another question. In the design with ISO3082, a 100pF capacitor is connected from the Driver Input to GND for both transceivers, and a 300Ω resistor is placed in series with this capacitor (CD = 100pF). What is the reason for adding this resistor?

I would appreciate your insights.

Thanks,
