Sampling rate

[allegro]

I use a **broken link removed** that its input sampling rate is DCLK/8 and its Digital Filter Output Word Rate is DCLK/1024.

I wonder, what's Digital Filter OWR, and what does it do?

The Output Word Rate is simply the frequency of the output words from the device. Each word contains the calculated data.

Thanks.
So basically you need to wait 1 / [DCLK/1024] for a single input sampling to be received at the ADC's output?

The chip apparently uses 1024/8 = 128 input samples to generate one output word. And you do have to wait DCLK/1024 clock counts for each output word.
