It integrates a divider, so you can generate sub-rate clocks from a higher-frequency reference without an extra chip. The differential input and output path (Yes/Yes) keeps noise rejection high, critical when routing clocks across a board with mixed-signal content. The supply range is tight: 3.15V to 3.45V. That means the 3.3V rail needs to be within ±4.5% — a standard LDO or switcher with 1% tolerance will hold it, but a noisy rail or one that droops under load risks jitter or output failure. ## Package and footprint — what the 48-WQFN demands ## Sourcing — active production, no end-of-life watch","metaTitle":"LMK01010ISQ/NOPB Clock Buffer 1.6 GHz LVDS Fanout - TI","metaDescription":"Texas Instruments LMK01010ISQ/NOPB fanout buffer, 1.6 GHz max, 1:8 LVDS outputs, industrial temp.

The /NOPB suffix indicates lead-free (RoHS) plating. If your existing BOM uses the non-NOPB variant, verify the board-level solder profile — the NOPB version requires a higher reflow peak temperature. Electrically they are identical."},{"question":"Does the LMK01010ISQ/NOPB require external termination resistors for the LVDS outputs?","answer":"Yes, standard LVDS termination applies. Each differential output pair needs a 100-ohm termination resistor placed as close to the receiver input as possible. The buffer itself does not include on-die termination. The datasheet (TI literature number SNAS480) shows the recommended termination scheme."},{"question":"What is the difference between LMK01010ISQ/NOPB and CDCLVP1204RGTR?","answer":"The CDCLVP1204 is a 2:4 fanout multiplexer with LVPECL outputs, while the LMK01010ISQ/NOPB is a 1:8 fanout buffer with LVDS outputs. The CDCLVP1204 accepts multiple input types (LVCMOS, LVDS, LVPECL, LVTTL) and runs from a 2.375V supply. The LMK01010ISQ/NOPB has a fixed 1:8 ratio and a tighter 3.15V-3.45V supply. They are not drop-in replacements — the output logic family and supply voltage differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMK01010ISQ-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/LMK01010ISQ-NOPB when reusing this data.
