MEMS clock source for commercial boards
Unlike a quartz crystal oscillator, the MEMS resonator is factory-trimmed and does not require external load capacitors — the frequency accuracy (±50 ppm) is set at the die level, so the BOM saves two passives and the layout avoids the stray-capacitance sensitivity of a crystal pair.
Commercial temperature and 4-pin SMD footprint
The 4-SMD, No Lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm, a common footprint shared with many quartz oscillators, so a board designed for a standard 5x3.2 mm XO can accept this MEMS part without layout changes.
Microchip lists the DSC1030BC1-016.0000 as Active.
