It operates from a 3.135V to 3.465V supply and is housed in a 40-VFQFPN (5x5) package rated for 0°C to 70°C commercial temperature range. ## 1:6 ratio — what it means for the clock tree With a 1:6 input-to-output ratio, this buffer drives up to six downstream devices — PCIe root complexes, switches, or QPI links — from a single reference clock. The differential input and HCSL output path (both differential) preserves signal integrity across the fanout, critical for keeping jitter within PCIe Gen3/Gen4 budgets. ## Active and ROHS3 — no lifecycle surprises The 9ZXL0651AKLF carries an Active product status with ROHS3 compliance.","metaTitle":"9ZXL0651AKLF PLL Clock Buffer, 1:6 HCSL for PCIe/QPI","metaDescription":"9ZXL0651AKLF PLL-based clock buffer with 1:6 HCSL outputs for Intel QPI and PCI Express. 3.135V–3.465V supply, 40-VFQFPN.
