T1040 Design Query

[gokulkrishnan]

Hi,

i am using the T1040 QorIQ processor for a design. But I am unable to find details regarding the current requirement of each rail and the hardware design guide for the chip. Can someone help me with this?

The T1040 power consumptions for each of the supply voltages are provided in the T1040 Data Sheet, 3.5 Power characteristics:

Hi,

In the datasheet I was able to find the power requirements for VDD vDDC and SIVDD but not for any other rail like:

AVDD_PLAT, AVDD_CGA1, AVDD_CGA2, AVDD_D1  etc. Could you help me with the current rating for the other rails. Correspondingly i can use a required power supply. In the reference schematics, I was able to find a few current requirements like for 1.8V, 2.5V, 1,35V etc. 

So is there a table or a document that contains the information I was looking for.

Regards

AVDD power consumptions are provided in the processor's Data Sheet, Table 12. I/O power supply estimated values.

Hi,

I was unable to find the current requirement for the rail USB_SVDD1 and USB_SVDD2. Could you help me with this.

The USB_SVDD1 and USB_SVDD2 are powered from the VDD. Their power consumption is negligible comparing to the core and platform.

Hi, 

Thank You

Hi,

The system clock DIFF_SYSCLK has a maximum input voltage of 1.8V ?

Is there any specified oscillator that is recommended fro the same with 100MHz and +/- 50 ppm?

It is reasonable to create new thread if the question is not a direct followup for the original one.
