Part Number: LMK04110 We are using the LMK04110 with 100M Hz as input with the same as output and the variation possible is 5600ppm. What should be my VCXO frequency?
Hi Satoshi-San,
A 148.5 MHz or 148.5 / 1.001 MHz signal can be cleaned up using LMK04110 with a 27 MHz off-the-shelf VCXO. PLL dividers would need to be re-configured when the reference clock is switched to a new frequency. I have set the configurations for…

What are you phase noise or jitter requirements with integration bandwidth?
Based on the frequency accuracy requirement, you'll at least need a TCXO as your reference clock. Depending on your…
Hello Ron,
Sorry for your trouble.
Two issues are going on here.
1) The LMK0482x profiles for the CDT does not support the SYSREF divider. So the max divide is 32 which doesn't allow it to find 19.2 MHz.
- A workaround is to put a multiple of this…
