20 MHz MEMS oscillator with AEC-Q100 qualification
The DSC1001DI2-020.0000 is a 20 MHz XO (Standard) oscillator built on a MEMS resonator rather than a quartz crystal, producing a CMOS output. It carries AEC-Q100 qualification, meaning it has passed the automotive-grade reliability stress and temperature cycling tests required for deployment in vehicle cabin and chassis domains. The MEMS base resonator gives this oscillator inherent resistance to shock and vibration compared to quartz, and it starts up faster — a practical advantage in automotive ignition cycles or industrial equipment that sees frequent power-on events.
Supply voltage flexibility and standby power
Maximum supply current is 6.3 mA at 20 MHz. A standby (power-down) function drops the supply current to 15 µA max, allowing the oscillator to be gated off during system sleep modes without a separate load switch.
Temperature range and frequency stability
Frequency stability is ±25 ppm across the full temperature range, which is tight enough for CAN, LIN, and most 10/100 Ethernet clocking without external trimming.
