The MEMS base resonator eliminates the quartz crystal's mechanical fragility and startup delay; this oscillator is rated for the shock and vibration profile of automotive and industrial environments where a quartz can would fail. ## Supply voltage and output drive considerations The LVDS output is a differential pair requiring 100 Ω termination at the receiver; the 32 mA max supply current includes the output driver current into a 100 Ω load. When the enable/disable function pulls the output to high-Z, supply current drops to 22 mA max. The 6-SMD, no-lead package measures 5.00 mm × 3.20 mm with a seated height of 0.90 mm — a standard 5×3.2 mm footprint that matches many quartz oscillator land patterns, simplifying a drop-in replacement. It is suitable for both new design-ins and ongoing production builds.","metaTitle":"DSC1123BI5-125.0000 MEMS Oscillator – 125 MHz LVDS, AEC-Q100","metaDescription":"Microchip DSC1123BI5-125.0000 XO (Standard) MEMS oscillator, 125 MHz LVDS output, ±10 ppm stability, AEC-Q100 qualified, -40°C to +85°C, 6-SMD.","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":"Tube","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"125 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","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":"Is the DSC1123BI5-125.0000 a direct replacement for a quartz crystal oscillator?","answer":"Yes, in most cases. The 6-SMD, 5.00 mm × 3.20 mm footprint matches the industry-standard quartz oscillator land pattern. The MEMS resonator is a drop-in replacement electrically, but check the supply voltage range (2.25 V–3.63 V) and the LVDS output — the receiving IC must have an LVDS input. A quartz oscillator with a single-ended CMOS output would not be a direct swap without a board change."},{"question":"What is the exact output type of the DSC1123BI5-125.0000?","answer":"The output is LVDS (Low-Voltage Differential Signaling) per.
