The DSC1101AM2-156.2500 is a MEMS-based XO (Standard) delivering a 156.25 MHz CMOS output with ±25 ppm frequency stability across the full -55°C to 125°C military temperature range. Supply voltage range of 2.25V to 3.63V lets it run from a 2.5V or 3.3V rail without an external regulator — common in FPGA and SoC clock trees.
No successor or replacement has been issued; the DSC1101 series remains the recommended path for this 156.25 MHz MEMS oscillator requirement.
The MEMS resonator inside is less sensitive to board-level mechanical stress than a quartz crystal — fewer frequency shifts after reflow or under vibration.
