About LDO_SoC supply in i.MX6DQ.

Dear All,

Hello. Refer to "50.2 Digital LDO Regulators" in IM6DQRM(Rev.2).

There is below description.

"The SOC regulator powers the rest of the digital logic on the chip."

What is the "rest of the digital logic"?

And, what case increases current consumption in the logic?

Best Regards,

Keita

Hi Keita

SOC regulator powers powers HDMI_VP, SATA_VP, PCIE_VP

depicted on Figure 50-1.

>what case increases current consumption in the logic?

Current consumption in the logic is increased when logic

works on higher frequencies and temperatures, at low frequency

current is less, when some module clocks are gated with

CCM_CCGRn registers, then its current has lowest current consumption.

Dear Igor,

Hello. Thank you for your reply.

OK. Thank you.

Refer to below block.

What is "SoC" block? And, what case increases current consumption?

Hi Keita

SoC is other digial circuitry not depicted on Figure 50-1,

for example CCM. Its current consumption increases when,

for example, PLL frequency is increased.
