18 MHz MEMS oscillator with full military temperature range
The DSC1121CM1-018.0000T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a 18 MHz CMOS output from a 2.25V to 3.6V supply rail.
Supply, output, and control features
Frequency stability is ±50 ppm, adequate for most serial communication and general-purpose clocking without external tuning.
Housed in a 6-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the footprint matches standard 3.2x2.5mm oscillator pads — a direct drop-in for many quartz XO layouts. Surface-mount assembly with no lead formed under the package; the 6-pad layout includes two no-connect or ground pads that improve mechanical stability during reflow.
RoHS compliance is standard for the series; confirm at RFQ if a specific certificate is required.
