The ±50 ppm total frequency stability includes initial tolerance, temperature drift, and supply variation; sufficient for most digital logic and serial links without external trimming. Supply voltage range is 1.8V to 3.3V — single rail covers 1.8V, 2.5V, and 3.3V logic families without a separate regulator. ## Standby function for power-sensitive modules Useful for battery-backed ECUs or telematics units that must wake on a CAN or LIN message — the oscillator restarts within the datasheet's startup time. ## 4-SMD no-lead package — board layout note Housed in a 5.00 mm × 3.20 mm 4-SMD no-lead package, seated height 0.90 mm max. The land pattern matches standard 4-pin oscillator footprints; no via-in-pad required. Surface-mount reflow profile per JEDEC J-STD-020.","metaTitle":"DSC1001BI1-054.0000 MEMS XO – 54 MHz, AEC-Q100, CMOS, Active","metaDescription":"Microchip DSC1001BI1-054.0000: 54 MHz MEMS XO, CMOS output, AEC-Q100, -40°C to 85°C, ±50 ppm, 1.8V–3.3V supply.
