Why choose a MEMS oscillator over quartz for this 10 MHz clock
The DSC1001DI1-010.0000 is a 10 MHz MEMS-based XO (Standard) that eliminates the quartz crystal's startup reliability concerns — no load-capacitance mismatch, no cold-crank hesitation. It is suited for under-hood or cabin-domain ECUs where a quartz can's shock and vibration tolerance is marginal.
Standby power-down: when the clock must sleep
For a battery-backed module that wakes on a CAN or LIN message, this standby current is below the leakage floor of most input protection diodes. Active current is 6.3 mA max at 10 MHz — the MEMS structure draws less than a comparable quartz oscillator at the same frequency, which matters when the 1.8V rail is already tight.
Supply voltage flexibility and package footprint
The 1.8V to 3.3V supply range lets this oscillator drop into a 1.8V-core MCU clock tree or a 3.3V peripheral bus without a separate level translator. The 4-SMD, no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a low-profile footprint that fits under a shielding can or on a dense automotive ECU.
