33 MHz MEMS XO with AEC-Q100 qualification
The DSC1001CL1-033.0000T is a 33 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a CMOS output from a 1.8V to 3.3V supply rail. Its AEC-Q100 rating means it is qualified for automotive-grade reliability, covering -40°C to 105°C ambient — the under-hood and cabin temperature band where a standard commercial XO would drift or fail. The MEMS resonator replaces a quartz crystal, so there is no load-capacitance matching to worry about — the oscillator starts up faster and holds frequency across shock and vibration better than a quartz-based equivalent. Frequency stability is ±50 ppm over the full temperature range.
Active current and standby power
Active supply current is 7.2 mA max at 33 MHz — low enough for a battery-backed real-time clock or an always-on automotive body controller. When the standby (power-down) function is asserted, the disable current drops to 15 µA max, preserving the battery during vehicle sleep.
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The 0.50 mm pitch land pattern is standard for this form factor; the small footprint leaves room for decoupling caps on a dense automotive ECU board.
It is suitable for new designs and production builds. Sourced through independent distribution; quoted to order against the BOM quantity.
