SigCon Architect - DS110DF410 De-Emphasis level does not match the datasheet table.

Hi Team,

SigCon Architect seems to have some bugs in displaying DEM level in High Level Page. Could you please confirm ? I believe the datasheet value is true.

DEM setting does not match the value in the datasheet Table 13. Example below should show -3.9dB in High Level Page, as REG 0x15 = 0x54. It seems other setting also does not match the value in Table 13.

Hi Kawai-san. The customer is correct. When you enter a de-emphasis in the high level page and then check the register (0x15) in the low level page, the values in the applicable bits [6, 2:0] do not match those found in the datasheet in Table 13. This is true for all de-emphasis values except 0,-0.9, -1.5, -2, and -12.

My short term recommendation is to use the GUI low-level page to set the channel register 0x15 de-emphasis bits.
