Package is 6-SMD no-lead, 3.20 mm x 2.50 mm — a standard 3.2x2.5 mm footprint that matches many quartz oscillator pads, but the MEMS die has different decoupling needs: place a 100 nF ceramic within 2 mm of the supply pin to keep the internal PLL clean. ## Active production — no redesign pressure The DSC1123 series is an ongoing Microchip line; the DSC1123CI5-409.3750T can be designed in today and sourced for the full production run.","metaTitle":"DSC1123CI5-409.3750T – Microchip MEMS XO, 409.375 MHz LVDS","metaDescription":"Microchip DSC1123CI5-409.3750T: MEMS-based XO, 409.375 MHz LVDS output, ±10 ppm stability, -40°C to 85°C, AEC-Q100 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"LVDS","Series":"DSC1123","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"409.375 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","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 ~ 3.63V","Base Product Number":"DSC1123","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"32mA","Absolute Pull Range (APR)":"-","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/32c33983bfd645bac8d0b2ac5207c872.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the DSC1123CI5-409.3750T support enable/disable?","answer":"Yes — the Enable/Disable function is built in.
