IEEE 1588 feature on i.MX6Q Gigabit Ethernet MAC

Hi,

We want to use IEEE 1588 feature on i.MX6Q Gigabit Ethernet MAC. I have two questions:

1. We need i.MX6Q output 1pps signal. Which pin of the i.MX6Q can be used to output the 1pps? Can we use ENET_1588_EVENTx_OUT?

2. We need i.MX6Q ENET output 50MHz clock so that devices connected to the 1pps and 50MHz clock can get precise timestamp. Can ENET_1588_EVENTx_OUT be used as 50MHz clock output?

 

Thanks!
