MEMS-based clock source with wide temperature range
The DSC8121BM2: Total frequency stability of ±25 ppm over the entire temperature and voltage range means the clock edge jitter stays within a tight window — critical for a CAN bus or Ethernet PHY where cumulative timing error closes the link budget.
Programmable blank — user-configurable frequency
The DSC8121BM2 ships as a blank (unprogrammed) device — the user must program the target frequency using Microchip's programming tools before placement. 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.
