IMX6; NVCC_ENET = NVCC_RGMII (2.5V) ?

[michaelschaper]

Hi, this is my first IMX design at all and I'm a bit lost with all this reference manuals / schematics / datasheets.

The Ethernet Phy we've selected is Micrel KSZ9021RN, so I have to connect NVCC_RGMII to 2.5V source ( I found a helpful hint here in the forum).

To avoid the DC level shifter on ENET_REF_CLK (reference schematic: 2x68k + 1uF) I would like to know if it's possible to supply NVCC_ENET with 2.5V too.

Regards,

Michael

Hello,Michael,

     from datasheet of i.mx6dq:

you can use 2.5V to NVCC_ENET module. Please notice : VDDIO between ENET and Phy should be 2.5V.
