You need a Microtech TimeFlash programmer or a factory-programmed version (DSC8121xx prefix) for a ready-to-use oscillator. The blank part gives flexibility for low-volume prototypes or multi-frequency BOM consolidation. The land pattern matches the standard 6-pad footprint for MEMS oscillators in this form factor — no special via-in-pad or thermal relief required for the supply pins. Surface-mount assembly with a standard reflow profile; the MEMS die is hermetically sealed in the package, so no moisture sensitivity level (MSL) concern beyond the standard JEDEC level 1 handling.","metaTitle":"DSC8121CM2 MEMS XO, 10-170 MHz, CMOS, -55°C to 125°C","metaDescription":"Microchip DSC8121CM2 MEMS-based XO, 10 MHz to 170 MHz, CMOS output, ±25 ppm stability, -55°C to 125°C, 6-SMD.
