Other Parts Discussed in Thread: ADS52J90

Hi,

My customer is using ADS52J90.
He wants to use below condition.
Can customer use at K=4?

- JESD204B subclass 1
- 4 ADCS PER LANE
- ADC RESOLUTION 12 or 14 or 16

I think that this condition is enable to be satisfied Equation 2 in datasheet, then customer can have using case of K=4.
Is it correct?

Best regards,
Shimizu

Shimizu,

The main rule for the K value is that 17 < F * K. So, for N' or Serz of 16, then F=8 and so the minimum K is 3. The ADS device will default to the minimum K value. To force the K value, you can use two register fields in the device, Force_K and K_value_to_force. Here K = K_value_to_force -1.

Thanks,

Chuck Smyth
