Active MEMS oscillator for extreme-temperature timing
The DSC1121DM3-032.0000 is a 32 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a CMOS output across a -55°C to +125°C military temperature range.
Supply voltage spans 2.25V to 3.6V, so the same part can run from a 2.5V or 3.3V rail without a separate regulator — simplifies the power tree on a mixed-voltage board.
Housed in a 6-SMD No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight layout windows on multi-layer PCBs. Surface-mount assembly with no-lead terminations; the small body means the solder-paste stencil aperture should match the land pattern in the datasheet to avoid tombstoning during reflow.
