I have a custom board based upon Beaglebone Black. I am using Octavo OSD3358 and two Microchip LAN8710 PHY. The PHYs are wired RMII so I need a 50mhz clock. Because of my dual ethernet design, there will be a total of four clock signals that need supplied.
PHY-1 CLKIN (pin-5)
OSD3358 RMII1_REFCLK (pad H18)
PHY-2 CLKIN (pin-5)
OSD3358 RMII2_REFCLK (pad H16)
Is one crystal capable of providing four clock inputs?
Can you provide a link to a reference design using one crystal and four clock inputs?
I may want to use a oscillator instead of a crystal.
Can you recommend a manufacture and part number of an oscillator that is a good match for the LAN8710 and OSD3358?
Is one oscillator capable of driving all four clock inputs?
Do you have a reference design using oscillator(s)?
