It replaces quartz crystal oscillators in applications where vibration resistance, faster start-up, and wider temperature range matter — the MEMS resonator is inherently more rugged than a quartz blank. Output is CMOS, compatible with most digital logic families (3.3V and 2.5V). The enable/disable function lets the system gate the clock without a separate buffer — useful for power-saving sleep modes. Operating from 2.25V to 3.6V, this oscillator covers both 2.5V and 3.3V rails without a level translator. Frequency stability is ±10 ppm over the full temperature and voltage range (Absolute Pull Range). That is tight enough for most UART, I2C, and SPI links without needing a TCXO. Housed in a 6-VDFN package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The small footprint saves board space compared to a quartz can; the surface-mount package reflows with standard lead-free profiles. Supplied on Tape & Reel (TR) for automated pick-and-place assembly. Suitable for new designs and production builds.","metaTitle":"DSC1121CL5-033.3333T MEMS Oscillator 33.3333 MHz CMOS -","metaDescription":"DSC1121CL5-033.3333T XO (Standard) 33.3333 MHz CMOS MEMS oscillator from Microchip. ±10 ppm stability, 2.25-3.6V supply, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"33.3333 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"-","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~105°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"±10ppm","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1121CL5-033.3333T a drop-in replacement for a quartz oscillator?","answer":"Functionally yes — same 33.3333 MHz frequency, CMOS output, and enable/disable pin.
