Hi all

 

Is there any spec of CCM_CLK2 in i.MX6SoloX ?

 

I plan to use it for ENET2_TX_CLK, ENET2_RX_CLK and TX, RX clock for Mii of external device.

I concerned about  whether the CCM_CLK2 output can satisfy accuracy that is mentioned in 4.12.6.1.1 of IMX6SXAEC.

 

Here is a description in 4.12.6.1.1 of IMX6SXAEC.

The receiver functions correctly up to an ENET_RX_CLK maximum frequency of 25 MHz + 1%. There
is no minimum frequency requirement. Additionally, the processor clock frequency must exceed twice the
ENET_RX_CLK frequency.

 

Can I use CCM_CLK2 for ENET2_TX_CLK, ENET2_RX_CLK and TX, RX clock for Mii of external device ?
