Its 1.75 GHz maximum frequency covers RF synthesizer, high-speed ADC/DAC sampling, and SerDes reference clock applications where phase noise matters. The 2:7 input-to-output ratio means two independent input references can be conditioned and fanned out to seven LVCMOS, 2VPECL, or LVPECL outputs — enough to feed multiple clock domains on a dense mixed-signal board without external fanout buffers. ## 48-WFQFN exposed pad — thermal land is mandatory Housed in a 48-lead WFQFN with exposed pad (7x7 mm body), this part requires a thermal land on the PCB to draw heat from the die to the ground plane. A clean LDO ahead of this rail is recommended; switching ripple on the supply couples into the output phase noise. ## Industrial temperature and active lifecycle The industrial grade also covers the thermal rise inside a sealed enclosure. Texas Instruments lists this part as Active — no end-of-life notice or NRND flag. It remains a viable choice for new designs and production builds without a last-time-buy clock ticking.","metaTitle":"Texas Instruments LMK04002BISQE/NOPB Clock Conditioner","metaDescription":"Texas Instruments LMK04002BISQE/NOPB Clock Conditioner with integrated PLL, 1.75 GHz max frequency, 2:7 fanout.
