I am using the si890x, how do I achieve a 50ksps throughput knowing the sample rate is 2uS? Use SPI or UART? My baud rate is 115kbps.

- The si890x sample speed is higher than its communication speed. For si8900, the datasheet-specified baud rate is 234kbps, but AN635 discusses the automatic baud rate synchronization algorithm which can sync to as high as 520kbps. The data rate can be increased up to 50k sample per second rate if the SPI port is used, which run as fast as 2.5 Mbps.
