Operating temperature range -40 to +85°C covers cabin and most chassis-domain environments. For under-hood applications requiring -40 to +125°C, verify the grade level — this part is not specified beyond 85°C. ## Supply voltage range and output format for BOM fit Supply voltage range 2.25 V to 3.6 V spans both 2.5 V and 3.3 V logic rails without an external LDO — a single BOM line covers mixed-voltage designs. The CMOS output directly drives most MCU and FPGA clock inputs; no level translation needed. Useful for power-sensitive nodes that sleep the clock tree during idle periods. ## Package footprint and board layout notes Package is 6-SMD, No Lead Exposed Pad, 7.00 mm x 5.00 mm body, seated height 0.90 mm max. ## Lifecycle and ordering posture New designs can commit without immediate obsolescence risk.","metaTitle":"DSC1121AI2-019.4400C – Microchip MEMS XO, 19.4 MHz, CMOS","metaDescription":"Microchip DSC1121AI2-019.4400C active MEMS XO, 19.4 MHz CMOS output, ±25 ppm stability, 2.25–3.6 V supply, AEC-Q100 qualified, -40 to +85°C.
