Hi, All,

Could you tell me below?

can we use LMK00308 and LMK00338 as clock buffer and redriver?

as PCIe clock buffer , we've promoted below

since those different are jitter and clock frequency (400Mhz) and different type of Output.

beside of above, can customer use both of devices as clock buffer and redriver?

and tell us what's different between clock buffer and redriver ?

Thanks.

Best Regards.,

  • Hi Takahashi-san,

    I think clock redrivier and clock buffer are referring to the same thing, different people use different term. 

    You can promote both products to PCIe clock buffer/redriver application.

    Since PCIe clock is just 100MHz, LMK00338's jitter performance is good enough.
