Its supply voltage range of 2.25V to 3.6V lets it run directly from a 2.5V or 3.3V rail without an external LDO, simplifying the power tree. ## MEMS vs quartz — what changes on the BOM The Enable/Disable function (pin 1) pulls the output to high-impedance, reducing supply current from 58 mA (max) to 22 mA (max) — useful for power gating in multi-clock designs.","metaTitle":"DSC1122AE1-123.5200T – 123.52 MHz LVPECL MEMS Oscillator","metaDescription":"Active Microchip DSC1122 series MEMS XO, 123.52 MHz LVPECL output, ±50 ppm stability, 2.25V–3.6V supply, 6-SMD package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVPECL","Series":"DSC1122","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"123.52 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1122","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"58mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1122AE1-123.5200T/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC1122AE1-123.5200T lead-free and RoHS compliant?","answer":"The part is supplied in a 6-SMD package on Tape & Reel.
