The MEMS resonator's frequency vs. temperature curve is more linear than a quartz AT-cut's cubic curve, which simplifies the compensation circuitry and keeps the stability spec tighter over the full military temperature band. The 6-SMD, No Lead package measures 2.50mm x 2.00mm with a seated height of 0.90mm — this is a compact footprint that matches the industry-standard 2.5x2.0mm oscillator land pattern, so the PCB layout is the same as for any quartz oscillator in that form factor. Surface-mount mounting with a tape-and-reel delivery means the part is compatible with standard pick-and-place and reflow assembly. The MEMS die is encapsulated in the package, so no special handling beyond standard MSL precautions is required.","metaTitle":"DSC1121DM2-019.2000T MEMS Oscillator","metaDescription":"Microchip DSC1121DM2-019.2000T MEMS XO, 19.2 MHz CMOS output, ±25 ppm stability, -55°C to 125°C, 2.5x2.0mm 6-SMD.
