BF609_ACM_AD7984

Hi,

I have the ACM sample code(BF609_ACM_AD7984) of BF609 EZ-Lite with me, but not clear with it.

1. The throughout of ADC?

In AD7984 datasheet , the time between conversions of AD7984 is Tcyc(min)=750ns(fcyc=1.33MSPS).

In example code , the width , delay and period of GP timer 7 is 50, 50 and 200.

I think that the time between conversions of ADC is 200*SCLK cycle (200*Tsclk). fsclk=120MHz ,so Tcyc=200*(1/120000000)=1.67us. Is this right?

2. ADC_SUB_BUF_SIZE

In example code, ADC_SUB_BUF_SIZE=8096byte .

How determine this size?

 

Regards,
