• POL – Polarity Select – When this bit is selected, the polarity of the ADC sampling clock is
inverted
• Coarse Phase Adjust – Sets the approximate amount of coarse Aperture Delay applied.
• IPA – Intermediate Phase Adjust – Each code value in this field delays the sample clock by
approximately 11 ps. A value of 000b in this field causes zero adjustment. Maximum combined
adjustment using Coarse Phase Adjust and Intermediate Phase adjust is approximately 2.1 ns.
• Fine Phase Adjust – Sets the approximate amount of fine Aperture Delay applied.
Note: No changes will appear until the Write Adjust Reg button is clicked.
