Part Number: FDC2214

Dear，

The Maximum Output Rates (one active channel) of FDC2214 is 4.08Ksps.  What does the 4.08Ksps mean? How to change or configure  the output rate?

Best regards

    Hello Kailyn, 

    The output rate of 4.08Ksps is the fastest that the FDC2214 can provide a data output in the registers. There are a few things that impact this timing: the number of channels active, the reference frequency, the SETLLECOUNT register settings. Figures 13 and 14 show more of the timing involved with this sample rate. 

    Best Regards,
