This replaces up to four discrete quartz oscillators on the board, saving footprint and reducing BOM line count. Operating from 2.25 V to 3.6 V, this oscillator runs directly off a 2.5 V or 3.3 V rail without an external LDO — the wide input tolerance covers both common logic supplies in mixed-voltage systems. ## Output options and enable/disable control Output logic is selectable between HCSL and LVCMOS — HCSL for PCIe clock distribution, LVCMOS for general-purpose logic or FPGA clock inputs. Housed in a 20-VFQFN with exposed pad (5.00 mm × 3.20 mm footprint, 0.90 mm height), the package requires a thermal pad on the PCB for heat sinking — the exposed pad must be soldered to a ground plane to keep junction temperature within limits during continuous operation. ## Lifecycle and sourcing status","metaTitle":"DSC400-4111Q0112KI2 MEMS XO – 25 MHz & 100/156.25 MHz Quad","metaDescription":"Microchip DSC400-4111Q0112KI2: quad-output MEMS XO, 25 MHz (×3) + 100/156.25 MHz, ±25 ppm, 2.25–3.6 V, -40 to +85 °C, 20-VFQFN.
