The DSC1001BE1-012.0000 is a 12 MHz fixed-frequency XO (Standard) built on a MEMS resonator, delivering CMOS output with a frequency stability of ±50 ppm across its -20°C to 70°C operating range. It accepts any supply voltage from 1.8V to 3.3V, so the same BOM line can serve a 1.8V-core SoC or a 3.3V peripheral bus without a separate regulator tap.
Standby function and low-power sleep
In active mode the oscillator draws 16.6 mA max at the rated supply, which is typical for a 12 MHz CMOS-output MEMS XO driving a moderate capacitive load.
Package and board-fit details
Housed in a 4-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the DSC1001BE1-012.0000 fits standard 5×3.2 mm oscillator footprints — confirm the pad layout against the Microchip recommended land pattern. Surface-mount assembly with a tube shipping option; the package is lead-free and RoHS-compliant per the standard lead-free finish on Microchip's DSC1001 series.
