LMK00804B-Q1: Capability of 1.8V + Possible "Daisy Chain" of components

1.8V Clock input with this device

Yes, while you make sure that the input meets the V_IH and V_OH as specified on the data sheet.

Differential input (p.6):

Single-ended input (p.5):

2. They would also like to "Daisy Chain" first LMK00804B output to second LMK00804B Input according to the diagram below. Is this possible?

I will get back to you by next week. I have to look more into this for this device.

Hello Brandon,

Based on your diagram, yes, you can set up both LMK00804-Q1s like that to obtain 5 LVCMOS outputs from a automotive grade device. However, note that not all outputs will be synchronized. What are you trying to achieve with this setup? What are these clocks clocking?

Best,

Andrea
