About Basic Acquisition Window of ADC? (c2000)

Hi Everyone ,

I have basic question about acquistion window value and its calculation . In ADC block the SOCx acquisition window was entered as 14.

According to TI f28379D document from Texas Instruments Acquistion window duration=(SYSCLK)*(ACQPS+1) SYSCLK=5ns (200MHz)

According to this 14 value.

ACQPS+1=14 ---- > ACQPS=13 ? Isn't it ?

and

acquisition window duration = (5ns)*(14)=70 ns ? Isn't it ?

If I 'm mistake , can you correct my answers ?

Manythanks.

Hi Burak,

You are right. The 'SOCx acquisition window' parameter in the ADC block is equal to 'ACQPS+1'.

When this parameter is entered as 14 and SYSCLK=5ns (200MHz),

Acquistion window duration=(SYSCLK)*(ACQPS+1) = (5 ns)*14 = 70 ns.

Best Regards,

Ram Alla.
