Why this MEMS oscillator replaces a quartz can in automotive timing
The DSC1001DL2-016.0000T is a 16 MHz MEMS-based XO oscillator from Microchip's DSC1001 family, qualified to AEC-Q100 (cite:) and rated across -40 °C to 105 °C (cite:). That temperature grade covers under-hood and cabin electronics where a standard commercial oscillator would drift out of spec or fail the thermal cycle test. For a CAN bus or USB clock, that margin keeps the bit timing within the receiver's tolerance window.
The supply voltage spans 1.8 V to 3.3 V (cite:), so the same part number works on a 1.8 V MCU core rail and a 3.3 V peripheral bus without a level translator on the clock line. CMOS output (cite:) drives a single load directly — no AC-coupling or termination network needed for short traces. That sleep current is low enough to leave the oscillator powered in a battery-backed module without draining the coin cell.
Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a 0.90 mm seated height (cite:, cite:).
The DSC1001 series is Microchip's current MEMS oscillator platform, so the BOM line is not at risk of a last-time-buy window.
