This is not a fixed-frequency part; order the pre-programmed variant if you lack the programming infrastructure. Surface-mount mounting only — the package is not designed for through-hole or socketed use. The pad layout matches the industry-standard 5x3.2 mm oscillator land pattern.","metaTitle":"DSC8121BM2 MEMS XO, 10-170 MHz, CMOS, -55 to 125°C","metaDescription":"DSC8121BM2 MEMS-based XO, CMOS output, 10 MHz to 170 MHz, ±25 ppm stability, -55°C to 125°C, 2.25V-3.6V supply.
