Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a compact footprint that matches standard 5x3.2 mm oscillator pads, allowing a drop-in replacement for quartz XOs of the same size. No known successor; the DSC1224 series remains the current offering for this frequency/output combination.","metaTitle":"DSC1224BI2-100M0000T – Microchip MEMS XO, 100 MHz, HCSL","metaDescription":"Active Microchip DSC1224 series XO. 100 MHz, HCSL output, ±25 ppm stability, 2.5V-3.3V supply, -40°C to 85°C. 6-VDFN package.

The MEMS base resonator offers better shock resistance and no crystal aging, but the output type must match — this is HCSL, not LVDS or LVPECL.
