The 6-VDFN package (3.20mm x 2.50mm, 0.90mm height) fits compact PCB layouts, but the 0.50mm pitch demands careful fan-out on two-layer boards. ## Supply rail and stability margins The 2.5V–3.3V supply tolerance means the oscillator can share a rail with a 2.8V or 3.0V logic supply without an extra LDO — a BOM simplification when the system already runs on a 3.3V bus. Frequency stability of ±25ppm covers the full temperature range and supply variation, leaving headroom for the downstream PLL's jitter budget. Maximum supply current is 27mA typical — check the actual load capacitance on the CMOS output; the drive current scales with frequency and fan-out.","metaTitle":"DSC1211CI2-C0028 MEMS XO Oscillator – Microchip, CMOS","metaDescription":"DSC1211CI2-C0028 from Microchip: active MEMS XO, CMOS output, 2.5V–3.3V supply, ±25ppm stability, -40°C to +85°C. 6-VDFN package.
