The output is CMOS, which mates directly with most FPGA, MCU, and SoC clock inputs without a level translator. ## Temperature grade and supply flexibility This covers engine-bay electronics, downhole instrumentation, and satellite thermal cycling without a separate industrial-grade derating step. No external LDO or rail splitter needed when the clock tree straddles two voltage planes. ## Programmable frequency range and stability The available frequency range is 10 MHz to 170 MHz, with a total frequency stability of ±25 ppm. One order code covers the full span — the part is factory-programmed to the target frequency at the time of ordering, so a single BOM line can serve multiple frequency variants by specifying the programmed value at purchase. The footprint is standard for this class of MEMS oscillator — no special pad geometry or via pattern beyond the usual thermal pad for the exposed die paddle. Surface-mount, supplied in tube packaging. The 6-VDFN is a common oscillator footprint; layout engineers should confirm the pad pitch matches the existing land pattern for a drop-in replacement.","metaTitle":"DSC8121BM2-PROGRAMMABLE MEMS XO, 10-170 MHz, -55 to 125°C","metaDescription":"Microchip DSC8121BM2-PROGRAMMABLE MEMS XO, CMOS output, 10 MHz to 170 MHz, ±25 ppm stability, -55°C to 125°C, 6-VDFN.
