It delivers a 125 MHz LVPECL output — a differential signal that rejects common-mode noise and drives long PCB traces or 50-Ω terminated lines cleanly. Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an extra regulator. ## Sourcing and design-in posture Lifecycle status is Active — Microchip continues to produce this part, and it is suitable for new designs. The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Standard reflow profiles for lead-free solder work; the MEMS die is less sensitive to board flex than a quartz crystal, but keep the ground pad under the package solid for thermal and signal integrity. ## Temperature grade and deployment fit It fits networking switches, base stations, test equipment, and embedded processors that live in a controlled environment. Not rated for -40°C automotive or outdoor telecom; if the ambient drops below -20°C, look at the wider-temperature DSC1122 variants. For applications needing ±25 ppm or better, the DSC1122 family includes tighter grades; check the base product number suffix.","metaTitle":"DSC1122CE1-125.0000 MEMS Oscillator 125 MHz LVPECL –","metaDescription":"DSC1122CE1-125.0000: Microchip MEMS XO, 125 MHz LVPECL output, 2.25V–3.6V supply, Enable/Disable, ±50 ppm stability, -20°C to 70°C.
