Part Number: LMK00105 Tool/software: Hello team,
Datasyeet says VIH max of OSCin is 2.5V. What will happen in case OSCin input exceeds 2.5V but less than Vdd?
Best regards,
Hello,
Agreed, that could be too much of a load for this crystal. From equation 3 of the LMK00105 datasheet, C1 = (CL - CIN - CSTRAY) * 2 where CIN is 1 pF and CSTRAY could be around 1-3 pF depending on your PCB traces. Based on this, C1 and C100 in your…
Hello,
If the LMK00105 will be driving a trace or transmission line that has a 50 Ohm impedance, then the output driver is already well matched and I wouldn't expect reflections to be an issue. However, if the trace impedance is above 50 Ohms then adding…
Part Number: LMK00105 Hello team,
I have questions about LMK00105 below. Could you answer below?
Can I expect output to be fixed logic Low if we we force OSCin to be fixed logic High and input SEL selects OSCin?
Does the device have power sequence requirement…
Part Number: LMK00105 I need to drive a 50 ohm cable with a clean clock source and I would like to parallel multiple outputs of the LMK00105 to drive a series 50 ohm resistor and then the cable. Is this possible with this part?
Part Number: LMK00105 Hi Expert,
my customer is using LMK00105, the output current for VDDO in D/S 3.3V supply is typ 7 mA. do we have any max limitation, the application shown as below will reach to 35mA for each output.
in other E2E list, I see that…

Part Number: LMK00105 Hello,
I am considering to use the clock generator, LMK00105, and planing to use it under crystal connection.
I am chacking the datasheets of the LMK00105, but there is not infomation that I want to know.
Question:
How value is…
