The DSC8121BM2-PROGRAMMABLE: The silicon MEMS resonator eliminates quartz cold-start drift and vibration sensitivity — relevant for avionics, satellite payloads, and other high-reliability environments where a quartz crystal's aging or shock response could shift the centre frequency. 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.
