The DSC1001AC1-033.3333 is a MEMS-based XO (Standard) oscillator from Microchip Technology's DSC1001 series, delivering a 33.3333 MHz CMOS output with ±50 ppm frequency stability across its 0°C to 70°C operating range. The supply voltage range spans 1.8 V to 3.3 V, covering common digital rails without an external regulator, and the standby (power-down) function drops current draw to 15 µA max for battery-sensitive sleep modes.
Housed in a 4-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, this oscillator uses a standard surface-mount footprint that matches many quartz XO layouts — a direct drop-in for designs already using a 7x5 mm oscillator.
