It accepts LVCMOS, LVDS, or LVPECL inputs and can output LVCMOS, LVDS, 2VPECL, or LVPECL levels, making it a flexible choice for high-speed timing chains in base stations, test equipment, and data converters. The single-circuit PLL includes programmable dividers and multipliers, so you can synthesize a range of frequencies from a single reference. ## Input and output flexibility for mixed-signal designs With a 2:6 input-to-output ratio and differential signaling on both sides, this part can fan out a clean clock to multiple destinations while maintaining signal integrity. The ability to mix LVCMOS, LVDS, and LVPECL on the same device simplifies board-level routing when different logic families coexist on the same PCB. Housed in a 48-WFQFN with exposed pad (7x7 mm), the LMK04031BISQE/NOPB requires a solid thermal via stitch under the pad to keep junction temperatures under control at high output frequencies. Supply range is 3.15 V to 3.45 V, so a clean 3.3 V rail with ±5% tolerance is sufficient. Texas Instruments lists this part as Active with no announced end-of-life.","metaTitle":"LMK04031BISQE/NOPB Clock Conditioner with PLL, 1.57 GHz Max","metaDescription":"TI LMK04031BISQE/NOPB clock conditioner with PLL, 1.57 GHz max frequency, LVCMOS/LVDS/LVPECL I/O, -40 to 85°C, 48-WQFN.
