hi everyone:
i try to use max10 on chip adc to sample a image sensor output. the frequence is 1MHz.
i need to know when the max10 on chip adc switch from sample to the hold mode. in most adc, this is controlled by the CONVST signal.
acctually i can test the sample point by
1.applying a 1MHz sin signal to the adc input,
2.set the adc sample frequence to 1MHz, the adc will generate a valid signal every 1μs
3.put the sin signal and the adc valid signal on the oscilloscope
4.figure out the relationship between valid signal and the sample point.
the problem is :
1. i can not get the precise result
2. i can not make sure every max10 has the same result
but i still want to find the relationship between valid signal and the sample point on manual.
