The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — a practical advantage in portable instrumentation or equipment mounted on moving machinery. ## Supply voltage flexibility and power-down savings Maximum supply current is 58 mA when active; the standby (power down) function drops that to 95 µA, letting a microcontroller or FPGA gate the clock off during idle periods and save board power in duty-cycled designs. No pin-compatible second source is listed by Microchip, but the DSC1102 family includes other stability grades and output types if the system requirements tighten. Housed in a 6-SMD, No Lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The no-lead construction means the solder joints are under the package body — good for space savings, but the pad layout and stencil aperture need to match the land pattern in the datasheet to avoid open joints. Pin 1 orientation is marked on the package top; the part reflows on a standard FR-4 board with a 0.50 mm pitch. The exposed pad on the bottom provides a low-thermal-resistance path to the board, so a thermal via under the pad helps if the oscillator sits near a hot regulator.","metaTitle":"DSC1102DI1-125.0000 125 MHz LVPECL MEMS Oscillator","metaDescription":"Active XO (Standard) from Microchip, 125 MHz LVPECL output, ±50 ppm stability, -40°C to +85°C, 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":"DSC1102","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","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":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1102","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"58mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"95µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9eb455e34e1b4ad4aed847bfc84d48fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output type of DSC1102DI1-125.0000?","answer":"LVPECL — a differential, low-voltage positive emitter-coupled logic output.
