The DSC400-2222Q0022KI1 is a MEMS-based XO (Standard) from the DSC400 series, delivering four differential LVPECL outputs in a single 5.00 mm x 3.20 mm, 20-VFQFN package with an exposed pad for thermal management. It generates two independent frequencies — 125 MHz on outputs 1 and 4, and 100 MHz on outputs 2 and 3 — covering common reference clock requirements for FPGA transceivers, Ethernet PHYs, and SerDes blocks. ## Which supply rails and temperature range does it cover? The supply voltage spans 2.25 V to 3.6 V, so a single BOM line serves both 2.5 V and 3.3 V clock domains without a separate regulator. ## Is the part still in production? It remains a current production part suitable for new designs.","metaTitle":"DSC400-2222Q0022KI1 MEMS XO, LVPECL, 125/100 MHz, ±50 ppm","metaDescription":"Microchip DSC400-2222Q0022KI1: Active MEMS XO, four LVPECL outputs (125, 100, 100, 125 MHz), ±50 ppm stability, 2.25-3.6 V supply.

No external regulator is needed when the board runs a 3.3 V clock supply."},{"question":"What output type does the DSC400-2222Q0022KI1 provide?","answer":"All four outputs are LVPECL, a differential standard that requires proper termination (typically 50 Ω to Vcc - 2 V or a Thevenin equivalent) and AC-coupling if driving a CML or HCSL input."},{"question":"Can the DSC400-2222Q0022KI1 replace a quartz-based oscillator on an existing board?","answer":"The DSC400 is a MEMS resonator, not quartz. If the existing design uses a single-output quartz oscillator, the DSC400 offers four outputs, but the pinout and termination differ.
