159.375 MHz MEMS oscillator for industrial clock trees
Microchip DSC1121AI2-159.3750 is a standard XO (Standard) oscillator built around a MEMS resonator rather than a quartz crystal — the MEMS die is inherently more resistant to shock and vibration than a quartz blank, which matters for equipment that ships on a truck or runs on a factory floor. Supply voltage spans 2.25 V to 3.6 V, covering common logic rails — the Enable/Disable function drops supply current from 35 mA to 22 mA for power-sensitive sleep states.
Package footprint and board integration
Surface-mount package ships in tube — if your pick-and-place feeder expects tape-and-reel, confirm the tube-to-reel transfer with your assembler; the DSC1121 series is also available in tape on other order codes.
