MEMS oscillator for automotive clocking — 25 MHz, AEC-Q100, standby
The DSC1001CC1-025.0000 is a 25 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±50 ppm frequency stability across its 0°C–70°C operating range. It carries AEC-Q100 qualification — the automotive-grade stress and reliability testing that qualifies it for passenger-cabin or climate-controlled electronic modules where a quartz oscillator might drift under vibration or thermal cycling. The 1.8V–3.3V supply range lets the same oscillator serve 1.8V, 2.5V, or 3.3V logic rails, reducing BOM line count when the design spans multiple voltage domains.
When active, the oscillator draws 6.3 mA max (6.3 mA supply current), a low figure for a 25 MHz MEMS clock source.
Package and mounting — 4-SMD no-lead, 3.2mm × 2.5mm
Housed in a 4-SMD, No Lead package measuring 3.20mm × 2.50mm with a seated height of 0.90mm — a standard MEMS oscillator footprint that matches many quartz XO pads, simplifying a drop-in replacement.
The base product number DSC1001 covers a family of frequencies and stability grades — the CC1 suffix identifies this specific 25 MHz, ±50 ppm, 0°C–70°C variant. No pin-compatible second source is documented; the DSC1001 series is the only known cross-reference.
