The LVDS differential pair keeps jitter low over short PCB traces, and the ±50 ppm total stability covers the combined error from initial tolerance, temperature drift, and aging without external trimming. Supply voltage spans 2.25V to 3.63V, so the oscillator runs directly from a 2.5V or 3.3V rail without an intermediate regulator. ## AEC-Q100 qualification and industrial temperature range Product status is Active, meaning Microchip continues to manufacture and support the DSC1123 series for new designs. No last-time-buy window is in effect; the part can be quoted to order against production BOM quantities. Housed in a 3.20mm x 2.50mm 6-SMD no-lead package, the DSC1123CI1-156.2500 occupies roughly the same footprint as a standard 3.2x2.5 mm quartz oscillator — a drop-in replacement for designs already using that land pattern. Seated height is 0.90 mm max, which fits under a 1.0 mm keep-out zone on the opposite side of a PCB. For a battery-backed system, the 10 mA saving during sleep is modest but measurable.","metaTitle":"DSC1123CI1-156.2500 – 156.25 MHz LVDS MEMS XO, AEC-Q100","metaDescription":"Microchip DSC1123CI1-156.2500: 156.25 MHz LVDS output, 2.25-3.63V supply, ±50 ppm stability, -40°C to 85°C, AEC-Q100.
