This replaces up to four separate crystal oscillators, reducing BOM count and board area for multi-rail clock trees in networking switches, base stations, and industrial controllers. ## Output options and supply flexibility Each output can be configured as HCSL or LVCMOS, covering the two most common high-speed clock interfaces for PCIe, Ethernet, and FPGA reference clocks. The supply voltage spans 2.25V to 3.6V, so the same part works across 2.5V and 3.3V rails without a separate regulator. ## Industrial temperature and stability Confirm availability and current pricing at RFQ.","metaTitle":"DSC400-4144Q0054KI1 MEMS XO – 156.25/100/50 MHz, HCSL/LVCMOS","metaDescription":"Microchip DSC400-4144Q0054KI1: MEMS XO, 4 outputs (156.25/100/50 MHz), HCSL/LVCMOS, ±50 ppm, -40°C to 85°C, 20-VFQFN.
