It accepts LVCMOS, LVDS, or LVPECL inputs and provides the same output protocol options, with full differential input and output capability — so it fits into a wide range of clock trees without needing external level translation. The 3:15 input-to-output ratio means a single reference clock fans out to fifteen independent clock domains. For a system with multiple high-speed ADCs, FPGAs, or SerDes transceivers, this reduces the number of clock ICs on the board and simplifies the distribution layout. ## Supply and temperature — single-rail industrial operation Operates from a single 3.15 V to 3.45 V supply rail. No separate analog or digital supply needed — the internal LDOs clean the rail further, so a standard 3.3 V regulator with ±5% tolerance stays within the window. The pad is the primary thermal path; without proper soldering to the PCB copper, the junction temperature rises above the 85°C ambient limit even at moderate output loads. ## Active production — no obsolescence flag Sourced to order against RFQ through independent distribution; current pricing and lead time confirmed at quote time.","metaTitle":"Texas Instruments LMK04228NKDR Jitter Cleaner, 3.08 GHz, PLL","metaDescription":"Active TI LMK04228NKDR jitter cleaner PLL, 3.08 GHz max, 3:15 I/O, LVCMOS/LVDS/LVPECL, -40 to +85°C, 64-WQFN.
