The DSC1001AI2-014.7456T is a 14.7456 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across -40°C to 85°C. It is suited for under-hood ECUs, infotainment clocks, and ADAS sensor interfaces where a quartz oscillator's failure rate at high g is a known risk.
The supply voltage range spans 1.8V to 3.3V, so the same order code can populate a 1.8V MCU rail or a 3.3V FPGA bank without a second BOM line. Maximum operating current is 6.3 mA at 14.7456 MHz, which keeps self-heating negligible in the 7.0 mm × 5.0 mm 4-SMD package.
Active production — no design-in risk
The MEMS architecture also means the oscillator is not subject to quartz supply constraints or crystal aging drift.
