Hi Derek,
The LMK04828 can generate these separate frequencies. The SYSREF path can use the SYSREF divider to generate the lower clock frequency as needed. Additionally, your configuration would best be matched by the onboard Pulsor which can generated…
Hello Iouri,
1. you can use CDT http://www.ti.com/tool/clockdesigntool .
It helps with loop filter design. In the Loop filter Design window, you can specify the requested Bandwidth and phase margin -> which will provide a good loop filter component selection…
Hi Mario,
Did you mean LMX2531? Did you try using the National Clock Design Tool for device configuration/simulation?
You can download the tool from the link below

Make sure your PLL and Output divider settings are set accordingly for Dual PLL w/ 0-delay per section 9.2 of the datasheet:
To obtain reasonable PLL1 loop filter capacitor values, I suggest to use PLL1 PFD frequency of 1 MHz and CPout1 current of 0…
Hi Sammy Jeon,
You can achieve this using Digital Delay on LMK04906: http://www.ti.com/lit/ds/symlink/lmk04906.pdf
Operate the device in Single PLL mode (Page 4). Use a 19.44 MHz Crystal reference on OSCin.
Use Clock Design Tool for your frequency planning…
I will review at your CODELOADER configuration settings and let you know soon if the design is OK.
Did you use CLOCKDESIGNTOOL to calculate the loop filter values for PLL2?
For calculating power consumption, please refer to the current consumption table…
Other Parts Discussed in Thread: LMK04816 , CLOCKDESIGNTOOL I’m looking at using the LMK04816 as central piece of our clk module. The new clk block is attached.
It seems that the LMK04816 is just a very good fit….
the External clk is 10MHz; …
Other Parts Discussed in Thread: LMK04816 , CLOCKDESIGNTOOL Hello,
I plan to use the LMK04816 to clock several ADCs.
The input frequency of the LMK04816 can vary from 1kHz up to 100MHz, and the LMK04816 shall use it to make 10-80MHz sampling frequency for…
Other Parts Discussed in Thread: CLOCKDESIGNTOOL HI, I have a problem about a parameter(BW) in Loop Filter Calculator:
when i change the Fout, and keep the 'BW 'as 80khz, the filter parameter result will change, why???
