Interfacing AM3715 with LMK04808

Other Parts Discussed in Thread: LMK04808, AM3715

Is anyone aware of any special considerations for interfacing the LMK04808 Clock Generator/Jitter Cleaner and the AM3715?

Is there any additional hardware that needs to be added in order for the the AM3715 to talk to the LMK04808?

V/r,

Hi Jake,

How do you intend to connect it?

I was planning on using one of the SPI ports with the following connections.

MCSPIx_SIMO to DATAuWIRE
MCSPIx_CLK to CLKuWIRE
MCSPIx_CSy to LEuWIRE

Electrically there should be no problems if the AM335X SPI I/O cells are at 3.3V. From the uWIRE timings I see that typical access is 32-bit long, which is also supported by the McSPI. The only thing of concern would be if the timings with 3 extra clocks are required.
