LMK04832: Using multiple devices!

BobL

Part Number: LMK04832

Support, I need to use multiple devices in my design as I need more clock pairs. Can I just use one VCXO and supply DCLK to the 2nd device to phase lock the 2nd device?

HI Bob

Yes, you can use the OSCout from the first device instead of DCLK to exclude the PLL2 noise from the first device (although DCLKout can also be used)and feed it to the OSCin of the second device like shown below:
