It targets Intel QPI and PCI Express (PCIe) reference clock trees, where the PLL cleans up jitter from the source and synthesizes the output frequency up to 150 MHz. ## Package and reflow considerations The exposed pad also affects the solder paste stencil aperture — a typical recommendation is a 50-60% coverage pattern to avoid voiding under the pad. No MSL rating is listed on the record, but VFQFN packages commonly ship at MSL3, so a bake before reflow is prudent if the floor life has been exceeded.","metaTitle":"Renesas 9ZXL1950BKLF PLL Clock Generator, 1:19 HCSL, 150 MHz","metaDescription":"Active Renesas 9ZXL1950BKLF PLL clock generator with 1:19 HCSL fanout for Intel QPI/PCIe. 150 MHz max, 3.135-4.6V supply, 72-VFQFN.
