Other Parts Discussed in Thread: ADS8900B, C2000WARE
Hi all,
I am using ADS8900B ADC to digitize a high frequency signal (< 250 KHz) at the rate of 1MSPS (or 500 KSPS) throughput with F280048C. The 1 MSPS interrupt is generated from the CPUTimer0. The ADC data acquisition (generating CONVST, CS signal and reading data from SPI buffer after dummy write) itself is taking around 700ns. Whether this is a nominal value ?
I need to implement 4th order Band Pass Filter in F280048C. Whether timing margins will be met given the fact that the DSC maximum clock freq is 100 MHz. Are there any optimized functions to do this ? The "IIR5BIQ32" for N=2 takes around 48 cycles and "IIR_f32_calc" takes around 90 cycles.
Thanks n Regards,
Karthik R
