Housed in a 3.20 mm x 2.50 mm 6-SMD no-lead package, 0.90 mm seated height — the compact footprint suits dense PCB layouts where a quartz crystal plus oscillator IC would consume more board area. The MEMS resonator eliminates the quartz crystal's mechanical sensitivity to vibration and shock, making the DSC1122CI2-133.3300T a fit for industrial motor drives, outdoor telecom cabinets, and other environments where board-level vibration is a concern. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1122CI2-133.3300T MEMS Oscillator, LVPECL, 133.33 MHz","metaDescription":"Microchip DSC1122CI2-133.3300T XO (Standard) MEMS oscillator, LVPECL output, 133.33 MHz, ±25 ppm stability, -40 to 85°C, 2.25-3.6V supply.
