The LVDS differential pair keeps jitter low over board traces, which matters when the clock fans out to multiple loads on the same net. Rated across -40°C to +85°C with ±25 ppm frequency stability, the DSC1123AI2-156.2539 holds its timing over temperature without a quartz crystal's warm-up curve. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz blank — useful in automotive or industrial environments where the board sees mechanical stress. ## AEC-Q100 qualification and supply voltage range AEC-Q100 rated — this oscillator is qualified for automotive-grade reliability stress and PPAP. Supply voltage range is 2.25V to 3.63V, covering common 2.5V and 3.3V rails. The Enable/Disable function lets a GPIO pull the output to high-impedance and drop supply current from 32 mA max to 22 mA max — useful for power-cycled sensor nodes or multi-clock-domain power sequencing. Product status is Active — Microchip continues to manufacture and support this part. That means new designs can commit to this BOM line without a last-time-buy window, and existing production runs are not at risk of an abrupt supply cut.","metaTitle":"DSC1123AI2-156.2539 LVDS MEMS Oscillator 156.2539 MHz","metaDescription":"DSC1123AI2-156.2539 XO (Standard) LVDS output, 156.2539 MHz, ±25 ppm stability, AEC-Q100 qualified.
