It accepts LVCMOS, LVDS, or LVPECL on the input side and delivers LVDS or LVPECL on the output side, making it a clean fanout buffer for high-speed clock trees. Rated for a maximum frequency of 1.57 GHz, this part sits in the range of high-speed serial links — think 10G Ethernet, Fibre Channel, or backplane clock distribution where a single reference must drive multiple serializer/deserializer (SERDES) devices without skew. The 1:8 ratio means one input drives eight outputs, each differential pair carrying the same conditioned clock. This eliminates the need for multiple fanout buffers on the board and keeps the jitter budget tight across the distribution tree. ## Supply rails and temperature grade Operates from a 3.15 V to 3.45 V supply. That 300 mV window is tighter than a generic 3.3 V rail — the regulator feeding this part should be within ±5 % of 3.3 V to stay inside the spec. Housed in a 48-lead WFQFN with an exposed pad (7x7 mm). The 0.5 mm pitch QFN demands careful solder-paste stencil design to avoid bridging on the centre pad.","metaTitle":"Texas Instruments LMK03001ISQ/NOPB Clock Conditioner","metaDescription":"Active TI clock conditioner, 1:8 fanout, 1.57GHz max, LVDS/LVPECL outputs, 48-WQFN.
