800 MHz clock conditioning with integrated PLL
The LMK02002ISQ/NOPB is a clock conditioner IC from Texas Instruments that integrates a phase-locked loop (PLL) to clean up and regenerate clock signals up to 800 MHz. It accepts LVCMOS, LVDS, or LVPECL inputs and delivers LVPECL outputs, making it suitable for high-speed serial links, data converters, and FPGA reference clock trees where jitter performance is critical. With a 2:4 input-to-output ratio, the device can distribute two input references to four output paths, each synthesized through the PLL.
Housed in a 48-WFQFN exposed-pad package (7x7 mm body), the LMK02002ISQ/NOPB requires a thermal land pattern on the PCB for proper heat dissipation. Surface-mount assembly follows standard QFN reflow profiles. The device is available in both Tape & Reel and Cut Tape options, accommodating volume production as well as prototype or low-volume builds.
The base product number LMK02002 covers a family of clock conditioners; the suffix ISQ/NOPB indicates the industrial temperature grade and lead-free (RoHS-compliant) finish. No pin-compatible second source from another manufacturer is listed, so BOM risk is managed through TI's supply chain.
