Unlike quartz-based oscillators, the MEMS resonator handles shock and vibration better — relevant for avionics, downhole tools, or satellite payloads where a crystal can fracture or drift under G-load. Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the compact footprint fits tight PCB layouts, but the no-lead terminations require a solder-paste stencil aperture matched to the pad geometry for reliable reflow. The DSC1121 series is a current production line from Microchip, so this part can be designed in without worrying about a near-term discontinuation.","metaTitle":"DSC1121DM3-032.0000T MEMS XO 32 MHz CMOS ±20 ppm -55°C to","metaDescription":"Microchip DSC1121DM3-032.0000T: Active MEMS oscillator, 32 MHz CMOS output, ±20 ppm stability, 2.25-3.6 V supply, -55°C to 125°C.

For a 32 MHz clock that needs tight frequency stability without spread-spectrum modulation, the DSC1121 is the correct choice."},{"question":"Can I replace a quartz oscillator with the DSC1121DM3-032.0000T?","answer":"Yes — the DSC1121 is a drop-in MEMS replacement for standard 32 MHz CMOS quartz oscillators in the same 6-SMD footprint. The MEMS resonator offers better shock and vibration tolerance and faster startup, but the output type, supply voltage range, and frequency stability are compatible with most quartz-based designs."},{"question":"Is the DSC1121DM3-032.0000T RoHS compliant?","answer":"The part is listed with a standard RoHS compliance status — no non-RoHS variant is indicated in the product record.
