The DSC1121BM2-030.0000 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 30 MHz CMOS output with ±25 ppm frequency stability across the full -55°C to 125°C range. The 6-SMD, no-lead package (5.00mm x 3.20mm) reflows like any other passive, and the 0.90mm seated height fits tight card stacks.
Supply voltage and output type
The oscillator operates from 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without an external regulator. CMOS output drives standard digital loads directly — no level translation needed for most MCU or FPGA clock inputs.
No single-source risk — the MEMS oscillator market has multiple second-source options in the same footprint.
