The MEMS base resonator provides inherent shock and vibration tolerance compared to quartz, which is relevant for engine bay, transmission, and ADAS sensor modules where mechanical stress is a known failure mode. ## Supply range and enable/disable function Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V logic rails without an external regulator — the wide range simplifies BOM consolidation across multiple voltage domains. The Enable/Disable function allows the output to be tri-stated, reducing supply current from 35 mA max to 22 mA max — useful for power-sequenced designs or test modes where the clock must be gated without a separate clock buffer. ## Package and board-level fit 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, the footprint matches industry-standard 7x5 mm oscillator pads — a direct drop-in replacement for quartz XOs in the same form factor, provided the supply and output type are compatible. Product status is Active, meaning Microchip continues to manufacture and support the DSC1121AI2-135.1680 for new designs and volume production. Sourced through independent distribution, the part is quoted to order against the BOM quantity.","metaTitle":"DSC1121AI2-135.1680 MEMS XO – 131.168 MHz, CMOS, AEC-Q100","metaDescription":"Microchip DSC1121AI2-135.1680 MEMS oscillator: 131.168 MHz CMOS output, ±25 ppm stability, AEC-Q100 qualified, -40°C to 85°C.

However, the MEMS base resonator has different startup characteristics and supply voltage range (2.25 V to 3.6 V,) — confirm that the quartz oscillator's supply and output type (CMOS,) are identical before substitution.
