Hi team,

What's the meaning of Scale Per Step? Which one should we choose?

If we choose 3.125mV, it is

If we choose 9.375mV, it is

Why there is so big difference?

Hi Nison,

Scale per Step adjusts the DAC range of the DS160PR1601's EyeScan feature. Please refer to Section 3.6 of the Eye Scan with TI PCI-Express 5.0 Redrivers application note: https://www.ti.com/lit/an/snla435a/snla435a.pdf

Best,
David
