LMK04828: Clock Generator Recommendation

Part Number: LMK04828
Other Parts Discussed in Thread: LMK5B33216

Hello,

My customer is looking for a clock generator that can generate the following clock signals.

Could you recommend the most suitable TI clock product?

   - REF_CLK : 10MHz

   - Output Clocks

      1) LVDS output : 230.4MHz, 156.25MHz(2 port), 92.16MHz(2 port)

      2) LVCMOS(1.8V) : 25MHz (2 port)

      3) JESD : 230.4MHz(LVDS) & 3.6MHz(LVDS), 230.4MHz(LVPECL) & 3.6MHz(LVDS), 230.4MHz(LVPECL) & 3.6MHz(LVDS)

Thanks,

JH

    Hi, 

    Since you will need different frequency domains for the 156.25MHz / 25MHz and the 230.4MHz / 92.16MHz clocks, I would recommend using LMK5B33216 here. It has 3 PLLs so it can support your frequency plan, and it also has SYSREF divider paths to generate the JESD clocks. Do you have any specific phase noise or jitter requirements for these clocks? 

    Regards,
