Outputs are split between HCSL and LVCMOS, so this single oscillator can feed a PCIe reference clock (HCSL) and a logic-level system clock (LVCMOS) without a separate translator. Supply range is 2.25 V to 3.6 V, meaning it runs on a 2.5 V or 3.3 V rail without an extra LDO. The 20-VFQFN with exposed pad measures 5.00 mm × 3.20 mm and stands 0.90 mm tall.","metaTitle":"DSC400-4111Q0112KI1 MEMS XO – Quad Output, HCSL/LVCMOS","metaDescription":"Microchip DSC400-4111Q0112KI1: MEMS XO, 4 outputs (25MHz x3 + 100/156.25MHz), HCSL/LVCMOS, ±50ppm, -40°C to +85°C, 20-VFQFN.
