That frequency ceiling puts it squarely in the range needed for high-speed serial data links, RF synthesizers, and base station local oscillators — not a general-purpose logic clock. It accepts and delivers LVCMOS, LVDS, and LVPECL signal levels, so it can interface directly with common FPGA clock inputs, SerDes reference clocks, or RF mixer LO ports without external level translators. The 2:7 input-to-output ratio means two reference inputs feed seven clock outputs, giving you fan-out for multiple board destinations. The core supply range is 3.15 V to 3.45 V — a tight window that demands a clean 3.3 V rail with ±5 % regulation. The supplier device package is 64-WQFN (9x9 mm) — the pad pitch is 0.50 mm, so a 4-layer board with thermal vias under the pad is the practical minimum for reliable soldering and heat dissipation.","metaTitle":"LMK04208NKDT – TI PLLatinum Dual PLL Clock IC, 1.536 GHz","metaDescription":"Texas Instruments LMK04208NKDT PLLatinum dual PLL clock IC.
