The MEMS resonator replaces the quartz crystal, offering better shock and vibration tolerance — a real advantage in industrial or portable gear where quartz can drift or fail under mechanical stress. ## Industrial temperature grade and supply range The supply voltage spans 2.25V to 3.63V, covering common 2.5V and 3.3V rails without a separate regulator. ## Standby function and disable current A Standby (Power Down) function drops the supply current to 95 µA max when the output is disabled — useful for battery-powered systems that gate the clock to save power. Active draw is 32 mA max at 171.8181 MHz. ## Package and board layout considerations Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm, with a seated height of 0.90 mm. Surface-mount reflow profile follows standard JEDEC MSL levels.","metaTitle":"DSC1103AI2-171.8181T MEMS LVDS Oscillator 171.8181 MHz -","metaDescription":"Active production MEMS XO (Standard) by Microchip Technology.

The key difference: MEMS handles higher shock and vibration (tested to 50,000 g and 70 g RMS per MIL-STD-883) without frequency shift, whereas quartz can exhibit microphonic sensitivity or drift under mechanical stress. The electrical interface (LVDS, supply range, output drive) matches quartz XO footprints."},{"question":"What is the difference between the DSC1103 and DSC1123 series?","answer":"The DSC1103 series offers LVDS output, while the DSC1123 series provides LVPECL output. Both share the same package, supply range, and MEMS resonator technology. Choose DSC1103 for LVDS-terminated clock trees (common in FPGA and SerDes reference clocks) and DSC1123 for LVPECL-terminated designs (often used in high-speed networking)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1103AI2-171.8181T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1103AI2-171.8181T when reusing this data.
