About C6678 termination supply VDDT1 / VDDT2

g.f.

Hi,

I have a question about C6678.

Is there any method to calculate the power consumption of VDDT1 and VDDT2
which are written In C6678 datasheet(sprs691c) page.112 Table 7-1 ?

I checked the spread sheet but there was no value for VDDT1 and VDDT2.

Best regards,

VDDT1 and VDDT1 are filtered connections to the CVDD1 power supply. The value for CVDD1 in the spreadsheet includes the current requirements for VDDT1 and VDDT2. Since we are not expecting these to be powered by a different source we don't characterize the current requirements separately.

Hi Bill,

Sorry for posting again.

I understand that in the C6678 spreadsheet, VDDT1/2 power consumption is include in the CVDD1 value.
But our customer wants to know VDDT1/2 power consumption which will be indication for pattern design.

I found following E2E post that is introducing the table which listed the VDDT1/2 maximum current value for C6657.

Is there any table for C6678?
