The MEMS resonator's aging characteristic is typically lower than a quartz AT-cut crystal's over the same period. The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm oscillator footprint that matches many quartz XO layouts. Surface-mount reflow profile follows standard lead-free solder profiles; no special bake-out required before assembly.","metaTitle":"DSC1121CM1-030.0000T – 30 MHz MEMS XO, AEC-Q100","metaDescription":"Microchip DSC1121CM1-030.0000T: 30 MHz CMOS MEMS oscillator, ±50 ppm stability, 2.25-3.6 V supply, AEC-Q100 qualified.

The 6-SMD no-lead package (3.2 mm x 2.5 mm) matches the footprint of many standard quartz oscillators. No external load capacitors are needed, unlike a bare quartz crystal."},{"question":"What is the frequency stability of the DSC1121CM1-030.0000T?","answer":"Frequency stability is ±50 ppm over the full -55°C to +125°C range. This keeps the 30 MHz output within 1.5 kHz of nominal — sufficient for most serial communication links without a separate TCXO."},{"question":"How do I enable/disable the output on the DSC1121CM1?","answer":"The Enable/Disable pin (pin 1 on the 6-SMD package) controls the output. Driving it high enables the output; driving it low disables the output into high-impedance state, reducing supply current to 22 mA max. The pin has an internal pull-up, so leaving it floating keeps the output enabled."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CM1-030.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CM1-030.0000T when reusing this data.
