At 120 MHz, ±50ppm represents an absolute frequency error of ±6 kHz — fine for digital logic clocks and most MCU PLLs, but worth checking against any precision-timed bus (PCIe reference clocks, for instance, tighten to ±300ppm or tighter depending on the spec revision). The MEMS resonator delivers this stability without the crystal's AT-cut angle sensitivity to board flex. ## Supply rail and power architecture The part draws up to 35 mA when oscillating and drops to 26 mA in disable mode. The enable/disable pin lets the firmware gate the clock during low-power states — a full oscillator shutdown saves the delta between those two current figures versus leaving it running continuously. ## Package and placement Tape-and-reel packaging is standard for high-volume SMT assembly. The no-lead format means coplanarity is not a concern the way it is with a gull-wing part — but verify the paste mask footprint before committing to a new board spin. ## Sourcing — active, quoted to order No official second-source or successor order code is listed for this specific part.","metaTitle":"Abracon ASEMPC-120.000MHZ-T3 XO Oscillator, 120 MHz CMOS","metaDescription":"MEMS XO at 120 MHz CMOS output, 2.25–3.6 V rail, ±50ppm stability, -20°C~70°C.
