It operates from a 2.25V to 3.63V supply, so it can run directly off a 2.5V or 3.3V rail without an extra LDO, and draws 50 mA typical at the supply mid-point. Housed in a 6-VDFN measuring 3.20mm x 2.50mm with a 0.90mm seated height, the package footprint is compact enough for dense PCB layouts but still hand-solderable with a fine-tip iron — just check the MSL before reflow; MEMS resonators are generally MSL 1, but confirm the reel label.","metaTitle":"DSC1212CI3-C0029T MEMS Oscillator – LVPECL, 2.25-3.63V","metaDescription":"DSC1212CI3-C0029T from Microchip Technology.
