Microchip DSC1001AL5-004.0000T is a 4 MHz MEMS-based XO (Standard) oscillator delivering a CMOS output with ±10 ppm frequency stability across the full -40 to 105 °C industrial range. Supply voltage spans 1.8 V to 3.3 V — a single BOM line can serve both 1.8 V core logic and 3.3 V peripheral domains without an external level translator on the clock input.
AEC-Q100 qualification and operating envelope
AEC-Q100 qualified — the part passed extended temperature cycling, ESD, and latch-up testing required for automotive PPAP submission. The 4-SMD, no-lead exposed-pad package (7.00 mm x 5.00 mm) suits automated surface-mount assembly; the exposed pad aids thermal conduction to the PCB ground plane.
