Unlike a PLL-based synthesizer, it has no internal phase-locked loop (PLL = No per the spec), so it's a pure jitter-cleaning and distribution path, not a frequency multiplier. It handles input signals in LVCMOS, LVDS, or LVPECL formats and outputs in LVDS or LVPECL, making it flexible for interfacing with FPGAs, SerDes transceivers, or high-speed ADCs that need a clean differential clock. The single 1.57 GHz maximum frequency covers most high-speed serial links (10GbE, PCIe Gen3, SATA) and RF sampling converters that run off a sub-1.6 GHz reference. ## Package, supply, and temperature — what matters for a design-in It lives in a 48-lead WFQFN with an exposed pad (7x7 mm body). That pad needs a thermal via array and a solid ground pour to pull heat out — the datasheet's recommended land pattern is worth following closely. The supply rail is tight: 3.15 V to 3.45 V. A local LDO or a low-noise 3.3 V supply with good regulation is the safe call. It's happy in a base-station cabinet, a test-equipment chassis, or an outdoor enclosure that sees sun load, but not under-hood automotive (that would need AEC-Q100). ## Sourcing and lifecycle — active, no end-of-life concern It's a current-production part that can be ordered through authorized distribution channels. The base product number is LMK03001, so any PCN or datasheet revision will carry that prefix. The /NOPB suffix indicates lead-free / RoHS-compliant plating (no Pb in the solder balls or finish).","metaTitle":"LMK03001DISQX/NOPB Clock Conditioner, 1.57GHz, 48-WQFN","metaDescription":"Texas Instruments LMK03001DISQX/NOPB clock conditioner, 1.57 GHz max, 1:8 fanout, LVDS/LVPECL outputs, -40 to 85°C.

This is useful when a single clean reference needs to feed multiple FPGAs, ASICs, or converters on the same board without adding separate clock buffers for each destination."},{"question":"Can I hand-solder the 48-WQFN package?","answer":"It's possible with a hot-air rework station and a fine-tipped iron for the perimeter leads, but the 0.5 mm pitch and exposed pad make it a moderate-difficulty hand-solder job. A pre-heater or hot plate under the board helps the pad wet properly. For prototyping, a QFN breakout adapter is a practical alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMK03001DISQX-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMK03001DISQX-NOPB when reusing this data.
