The DSC1001CL1-012.0000 is an XO (Standard) MEMS oscillator delivering a 12 MHz CMOS output from a surface-mount 4-VDFN package measuring 3.20 mm × 2.50 mm. It operates across a 1.8V to 3.3V supply range, making it compatible with both 1.8V and 3.3V logic domains without an external level shifter.
The wide 1.8V to 3.3V supply range allows the oscillator to be powered directly from a 1.8V core rail or a 3.3V I/O rail without a separate regulator.
Frequency stability and absolute pull range
The Absolute Pull Range (APR) is rated at ±50 ppm, which defines the frequency tuning window for applications that require fine adjustment, such as spread-spectrum clocking or synchronizing to a reference. The 12 MHz output is a common microcontroller and CAN bus clock rate, directly usable without external PLL multiplication in many designs.
