It operates from a 2.25V to 3.6V supply, covering both 2.5V and 3.3V rails without an extra regulator, and draws 58 mA max at 125 MHz. The MEMS resonator eliminates quartz start-up delays and is less sensitive to vibration — a practical advantage in networking switches, test equipment, and industrial controllers where the 125 MHz frequency is a common Ethernet reference clock. The wide 2.25V–3.6V supply range means the same BOM line can serve designs with 2.5V or 3.3V core logic — no need to qualify a separate voltage variant. Housed in a 6-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a standard footprint that matches many quartz oscillator pads.","metaTitle":"DSC1122BE1-125.0000T MEMS XO, 125 MHz LVPECL, Active","metaDescription":"Microchip DSC1122BE1-125.0000T: 125 MHz MEMS oscillator, LVPECL output, ±50 ppm stability, 2.25V–3.6V supply, -20°C to 70°C, 6-SMD.

However, LVPECL output requires proper termination (50 Ω to VCC-2V) and AC-coupling — the board must already support LVPECL or be designed for it. Confirm the termination network before substituting."},{"question":"What is the output type and supply voltage range?","answer":"Output is LVPECL. Supply voltage range is 2.25V to 3.6V, covering 2.5V and 3.3V rails.
