Supply voltage tolerance from 2.25V to 3.63V means the oscillator runs directly off a 2.5V or 3.3V rail — no extra LDO needed, saving one component per BOM line. ## AEC-Q100 qualification and temperature grade The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which is relevant for engine-bay or transmission-mounted modules. This is a current production part suitable for both new design-ins and ongoing volume builds — no last-time-buy window to manage. The Enable/Disable function (pin-controlled) lets the system shut down the oscillator to 22 mA max supply current in standby, useful for automotive sleep modes. Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — compatible with standard reflow profiles for automotive-grade assemblies. Supplied on Tape & Reel (TR) suitable for automated pick-and-place; the exposed pad aids thermal conduction to the PCB ground plane.","metaTitle":"DSC1123AI5-155.5200T Microchip MEMS XO, 155.52 MHz LVDS","metaDescription":"Microchip DSC1123AI5-155.5200T MEMS oscillator: 155.52 MHz LVDS output, ±10 ppm stability, 2.25V-3.63V supply, AEC-Q100, -40°C to 85°C.
