Supply voltage spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail without an intermediate LDO. ## 6-VDFN package – rework and footprint notes The 6-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a low-profile, small-footprint oscillator. The exposed pad underneath is the thermal and ground plane; make sure the PCB pad has a via array to the ground layer to keep the junction temperature down. Reworking this package is straightforward with hot air — the VDFN has visible side pads and a clear pin-1 chamfer. The small thermal mass means it reflows quickly.","metaTitle":"DSC1121CL5-061.4400T MEMS XO – 61.44 MHz, CMOS, ±10 ppm","metaDescription":"Microchip DSC1121CL5-061.4400T MEMS oscillator: 61.44 MHz CMOS output, ±10 ppm stability, 2.25V-3.6V supply, -40°C to 105°C, 6-VDFN 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":"CMOS","Series":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"61.44 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","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~105°C","Current - Supply (Max)":"22mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"35mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1121CL5-061.4400T/alternatives.json"},"ai":{"faq":[{"question":"Is DSC1121CL5-061.4400T a MEMS oscillator?","answer":"Yes — the base resonator is a MEMS die, not a quartz crystal.
