1.296 GHz clock conditioner with integrated PLL
The Texas Instruments LMK04000BISQE/NOPB is a clock conditioner that integrates a phase-locked loop (PLL) to clean and distribute timing references up to 1.296 GHz. It accepts LVCMOS, LVDS, or LVPECL inputs and provides LVCMOS, 2VPECL, or LVPECL outputs across a 2:7 input-to-output ratio. This part is designed for systems that need low-jitter clock generation and fan-out — think wireless base stations, networking switches, and high-speed data converters where the clock is the noise floor.
Industrial temperature and supply tolerance
The supply range is tight at 3.15 V to 3.45 V — a 3.3 V rail with ±5 % regulation keeps it within spec.
