33 MHz MEMS oscillator with automotive-grade qualification
The DSC1001AI1-033.0000T is a 33 MHz XO (Standard) from Microchip's DSC1001 series, built on a MEMS resonator rather than a quartz crystal. Its AEC-Q100 rating means it has passed the temperature cycling, ESD, and reliability stress tests required for automotive deployment — a step up from commercial-grade oscillators that lack PPAP documentation. The CMOS output interfaces directly with most digital logic families without level translation, and the standby (power down) function drops supply current to 15 µA max — useful for modules that sleep between CAN bus wake events.
Supply voltage flexibility and temperature range
The oscillator operates from 1.8V to 3.3V, covering the common digital rails used in automotive ECUs, industrial controllers, and telecom gear. A single BOM line can serve a 1.8V FPGA bank and a 3.3V microcontroller without a separate regulator. The ±50 ppm frequency stability holds the clock edge within tight margins across this range.
