LMK04828: Output frequency of LMK04828?

HENRY JUNG
Expert 2030 points

Part Number: LMK04828
Other Parts Discussed in Thread: LMK04208, LMX2571

Dears.

We are reviewing LMK04828.
Our clock structure concept uses JED204B.
The LMK04828 will supply the ADC, DAC and FPGA.
CLKIN is 30.72MHz.
The frequency output is as follows.

Can I output the frequency with the LMK04828?

Recommend other clock products capable of frequency output.

A lot of frequency output ports are needed.

Is it possible to synchronize multiple LMK04828s?

Thank you

    Dear Henry,

    I would recommend you use our webench tool which will design a clock tree based on your frequency requirements. I quickly ran your frequencies in our tools and it returned a few suggestions including LMK04208 and LMX2571 however it did not include LMK04828 with the sysref feature. I recommend you work with webench.

    For synchronization, please send us an email at clock_support@list.ti.com and we will send you an preliminary app note for synchronization with LMK04828. Just mention your request in the email.

    Regards, Simon.
