It takes a single crystal input and generates up to 19 HCSL outputs at frequencies up to 146.7 MHz, making it the central clock distribution device on a Romley-generation motherboard or server blade. The 1:19 fanout ratio means one crystal reference feeds nearly two dozen differential clock lanes—saving multiple discrete buffers and reducing jitter accumulation. ## Supply voltage and temperature range Operates from a 3.135 V to 3.465 V supply. The commercial temperature range is 0 °C to 70 °C. ## Output type and differential signalling All outputs are HCSL (High-Speed Current Steering Logic), the standard differential signalling for PCIe reference clocks. The input side is single-ended (crystal), while the output side is differential (Yes/No for input/output respectively). This is a common architecture: a clean crystal oscillator feeds the PLL, and the PLL generates multiple differential pairs. The differential outputs reduce common-mode noise coupling on long board traces to PCIe slots or chipset. ## Lifecycle and sourcing reality Listed as active with ROHS3 compliance. No end-of-life notice or last-time-buy window applies to this order code.","metaTitle":"932SQ420DKLFT Clock Synthesizer, PLL, HCSL, 146.7 MHz","metaDescription":"932SQ420DKLFT PLL clock synthesizer with HCSL outputs, 1:19 fanout, 146.7 MHz max, for Intel Romley.
