The CMOS output drives a single-ended clock input directly — no external termination resistor needed at the source, though a series damping resistor at the oscillator output is standard practice if the trace is longer than 25 mm. ## Power budget: 7.2 mA active, 15 µA standby Active current is 7.2 mA max at 27 MHz across the full 1.8V–3.3V supply range. For a battery-powered sensor node that sleeps most of the time, that standby current is below the self-discharge of a CR2032 coin cell. That is the automotive Grade 3 temperature band — suitable for cabin electronics, infotainment, and ADAS sensor modules that sit inside the vehicle envelope but not directly on the engine block. The MEMS construction also passes the AEC-Q100 mechanical shock and vibration tests more easily than a quartz oscillator. 4-SMD no-lead package, 3.20 mm x 2.50 mm, 0.90 mm seated height.","metaTitle":"DSC1001CI2-027.0000 MEMS XO 27 MHz CMOS AEC-Q100 - Microchip","metaDescription":"Microchip DSC1001CI2-027.0000: MEMS XO, 27 MHz, CMOS output, ±25 ppm stability, -40°C to 85°C, AEC-Q100.

For a different frequency, the base product number DSC1001 with the desired frequency suffix is a direct drop-in. No second-source MEMS oscillator from another vendor is pin-compatible without checking the standby and output enable pin assignments."},{"question":"Can DSC1001CI2-027.0000 be ordered in tape and reel packaging?","answer":"The evidence lists the package as Tube.
