Automotive-grade MEMS timing for 4 MHz reference clocks
The DSC1001CI3-004.0000 is a 4 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, qualified to AEC-Q100 — the automotive IC reliability standard. The 4 MHz CMOS output directly drives the clock input of a CAN transceiver, LIN controller, or MCU without an external buffer.
Standby power-down and wide supply flexibility
±20 ppm stability in a 3.2×2.5 mm footprint
The 4-VDFN package measures 3.20 mm × 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits dense automotive ECU layouts.
It is available for design-in and volume production.
