MEMS oscillators typically survive 50 000 g shock and 70 g vibration, a step up from quartz for equipment that ships or operates in high-vibration environments. ## Package and board layout notes The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The enable pin is active-high; leave it pulled high through a 10 kΩ resistor if the function is unused.","metaTitle":"DSC1123CI2-333.3300T Microchip MEMS XO, 333.33 MHz LVDS","metaDescription":"Microchip DSC1123CI2-333.3300T: 333.33 MHz LVDS MEMS oscillator, ±25 ppm stability, 2.25-3.63 V supply, enable/disable, industrial temp.

The MEMS resonator gives faster start-up (typically under 5 ms vs 10 ms for quartz) and better shock/vibration tolerance. The LVDS output is differential, so the receiving device must have an LVDS input — it will not drive a single-ended CMOS load without a level translator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123CI2-333.3300T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123CI2-333.3300T when reusing this data.
