Denafrips Terra Clk with Iris DDC?


I'm curious if anyone out there is using a Denafrips Terra clock with their Iris DDC?

The Terra clock is $1315 US and the Iris is $563 US, so there's a bit of an odd mismatch there.   That said the Iris does have clock inputs and only for 45 and 49 MHz as Denafrips prefers. 

If anyone out there has done this, what were your impressions?  How did you incorporate the units into your system?

thank you
