Clock distribution for high-speed serial links
The LMK03000DISQE/NOPB is a precision clock conditioner from Texas Instruments that accepts LVCMOS, LVDS, or LVPECL inputs and delivers a 1:8 fanout of conditioned LVDS or LVPECL outputs, with a maximum output frequency of 1.296 GHz.
Fanout architecture and signal compatibility
With a 1:8 input-to-output ratio and fully differential signal paths (both input and output are differential), the part can distribute a single conditioned clock to eight destinations without adding skew from separate buffers. The device does not contain a PLL — it is a clock conditioner, not a synthesizer, so the output frequency is the same as the input; the conditioning cleans up jitter and reshapes the signal to LVDS or LVPECL levels.
