The enable/disable function lets the system gate the clock output without cycling the supply — useful for power-saving modes in ECU or sensor modules. It is suitable for both new designs and ongoing production replenishment. The part ships on Tape & Reel (TR), which is the standard format for automated pick-and-place. ## Supply voltage and stability margins The supply range is 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails with margin. The ±25 ppm frequency stability holds across the full temperature and voltage range — no external trim capacitor needed. Maximum supply current is 32 mA when enabled, dropping to 22 mA in disable mode. The LVDS output is a differential pair, so the receiver sees a clean 350 mV swing into a 100-ohm termination — standard for FPGA and SerDes reference clocks.","metaTitle":"DSC1123DI2-148.5000T – 148.5 MHz LVDS MEMS XO, AEC-Q100","metaDescription":"DSC1123DI2-148.5000T: 148.5 MHz LVDS MEMS oscillator, AEC-Q100 qualified, ±25 ppm stability, 2.25-3.63 V supply, enable/disable.
