VDD_SOC_IN

Hello,

 

We are developing an i.MX6 SOM that is designed to have common hardware for the SOLO, Dual, and Quad processors.  We need to increase LDO_SOC to 1.225 to operate the VPU above 264MHz. Two questions have arisen,

 

1 - We noticed that there seems to be mention of reducing DDR jitter if LDO_SOC is 2.275V is this important?

2 - We were considering increasing the VDD_SOC_IN to 1.45V to margin the input above the drop in the internal LDO. Is this reasonable?

 

Thanks for your help,

 

Best Regards,

 

BW
