The 2.25V to 3.63V supply range covers both 2.5V and 3.3V rails, so the same BOM line works across voltage domains without a separate regulator tap. The OEM auditor will look for the AEC-Q marking on the reel label and the PPAP documentation; this part carries that qualification, not just a 'capable' claim. ## Active production — no last-time-buy window Listed as Active by Microchip. ## MEMS resonator, 6-SMD footprint, surface-mount The 6-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. ## LVDS output and Enable/Disable pin details LVDS output provides a differential 350 mV swing typical into a 100-Ω termination — the receiver must be LVDS-compatible. This pin is useful for test isolation or power gating in multi-clock systems.","metaTitle":"DSC1123AI2-156.2539T Microchip 156.2539 MHz LVDS XO AEC-Q100","metaDescription":"DSC1123AI2-156.2539T: Microchip MEMS XO, 156.2539 MHz, LVDS output, ±25 ppm stability, AEC-Q100, 2.25-3.63V, Active.
