CLOCK-TREE-ARCHITECT: Clock generator recommendation

Hi Basel, 

Do you have any requirements for clock frequency, output type (ex: LVCMOS, LVPECL, HCSL, etc.) and jitter performance? Based on your description I expect that LMK3H0102 might work for your use case.

In fact I don't have any requirements from the client, the only thing is to that he wants both MCUs run on the same clock 

Thanks for your suggestion, but I found this drive a differential clock, and I want to feed a the two MCUs through the XO clock pin

Hi Basel, 

LMK3H0102 can be configured to provide 2 single-ended, LVCMOS clocks that are in phase.

Adding to my other reply, if you want a non-programmable solution you can also used a fixed-frequency oscillator (like LMK6C or CDC6C) to drive a 1:2 fanout buffer (such as LMK1C1102). The outputs from the buffer will be synchronized and this setup wouldn't require any programming or other device configuration.

Connor
