Its 1.536 GHz maximum frequency makes it suitable for clocking high-speed ADCs, DACs, and RF converters where jitter directly impacts SNR. The 2:14 input-to-output ratio means a single clean reference can feed an entire clock tree — a base station or radar receiver might use one LMK04803 to clock the ADC, FPGA, and backplane logic from a single oscillator, reducing BOM count and board area. ## Industrial temperature and supply rails The supply range of 3.15 V to 3.45 V is tight — a 3.3 V rail with ±5% tolerance stays within bounds, but a noisy or poorly regulated rail may push the PLL out of lock; plan for a low-noise LDO feeding this device. Differential inputs and outputs are supported on both sides, which is the standard for high-frequency clock distribution — LVDS or LVPECL signalling keeps noise coupling low over long board traces. Single-ended LVCMOS is also available for lower-speed fan-out or legacy interfaces. Supply decoupling should follow the datasheet layout — typically 0.1 µF and 1 µF ceramics per supply pin, placed as close to the package as possible. The tight 3.15 V to 3.45 V supply range means the decoupling network must keep ripple below 50 mV peak-to-peak at the PLL charge-pump frequencies.","metaTitle":"LMK04803BISQ/NOPB PLL Jitter Cleaner – 1.536 GHz","metaDescription":"Texas Instruments LMK04803BISQ/NOPB PLLatinum jitter cleaner, 1.536 GHz max, 2:14 input:output ratio, LVCMOS/LVDS/LVPECL I/O, industrial temp -40°C to 85°C","metaKeywords":null},"attributes":{"series":"PLLatinum™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes","Type":"Jitter Cleaner","Input":"LVCMOS, LVDS, LVPECL","Output":"LVCMOS, LVDS, LVPECL","Series":"PLLatinum™","Package":"Tape & Reel (TR) Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"64-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.536GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"LMK04803","Ratio - Input:Output":"2:14","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"64-WQFN (9x9)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.7000","priceTiers":[{"qty":1,"price":"$19.70000","currency":"USD"},{"qty":10,"price":"$18.16900","currency":"USD"},{"qty":25,"price":"$17.35200","currency":"USD"},{"qty":100,"price":"$15.51470","currency":"USD"},{"qty":250,"price":"$14.80024","currency":"USD"},{"qty":500,"price":"$14.08574","currency":"USD"},{"qty":1000,"price":"$13.26918","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3321637a871fc7c90f0a6aea9d5b505c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK04803BISQ%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMK04803BISQ-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/LMK04803BISQ-NOPB when reusing this data.
