The DSC1001DE1-027.0000T is a 27 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output over a 1.8V to 3.3V supply range. This is a direct fit for always-on telematics units or keyless-entry receivers that need a clean wake-up clock.
When the standby pin is asserted, the oscillator stops and draws 15 µA max — low enough to leave the clock tree powered during a CAN bus sleep cycle without a dedicated load switch.
Yes, the DSC1001DE1-027.0000T includes a standby (power down) function. When enabled, the oscillator stops and the supply current drops to 15 µA max, making it suitable for battery-backed or sleep-mode applications.
Yes, the DSC1001DE1-027.0000T carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability stress tests and is suitable for under-hood and cabin applications.
The DSC1001DE1-027.0000T is a MEMS-based oscillator with the same 27 MHz frequency and CMOS output as many quartz oscillators. Its AEC-Q100 rating and standby function add features not found on all quartz parts. Confirm pin-compatibility and frequency stability (±50 ppm,) against your existing quartz oscillator before substitution.
