Hello,

What is the maximum throughput with this operating in FSK SPI Mode?

Is it determined by how quickly you can write to FSK_SPI_DEV_SEL?

Cheers,

Joe

Hi Joe,

Yes, SPI programming speed is one of the factors. The other factor is the loop bandwidth. Since we are modulating the PLL, the FSK update rate should, theoretically speaking, be less than the loop bandwidth.
