Dear Team,

Could you recommend TI CLK-GEN? after base on my project clk frequency/ jitter request spec as table list, many tks!!

Hi Jimmy,

It looks like your application would need some type of ultra-low jitter clock generator for the differential outputs, I am thinking that either the LMK03328 clock gen or LMK05318B DPLL could work. However I think our clock generators only support normal HCSL. We have some clock buffers that can output LP-HCSL so maybe a solution of clock gen + clock buffer will be required. I have paged our clock gen marketing expert for now.

Thanks,

Evan Su

Sorry for the delay here. I believe we covered the query in Email. Currently suggesting LMK5B12212.
