It operates from a single 3.3 V supply and draws 32 mA max while enabled; the disable function drops the supply current to 22 mA max, useful for power-gating the clock tree in a battery-powered system. ## Industrial temperature grade and 6-VDFN footprint The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that leaves room for adjacent decoupling caps on a dense PCB layout.","metaTitle":"DSC1123DI1-054.0000T MEMS Oscillator 54 MHz LVDS - Microchip","metaDescription":"DSC1123DI1-054.0000T XO (Standard) from Microchip, 54 MHz LVDS output, MEMS resonator, -40°C to 85°C, 6-VDFN.

The key practical difference: MEMS oscillators have lower aging drift, better shock and vibration tolerance, and no need for external load capacitors. The DSC1123DI1-054.0000T's ±50 ppm stability is comparable to a standard quartz XO, but the MEMS construction eliminates the quartz blank's frequency shift over time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123DI1-054.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123DI1-054.0000T when reusing this data.
