Supply voltage spans 2.25 V to 3.63 V, so it runs off a 3.3 V or 2.5 V rail without a separate regulator, and draws 32 mA max — light enough that a shared rail with other digital loads won't sag under the oscillator's transient. Housed in a 6-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight channel spacing on a multi-gigabit backplane or a sensor interface card. Surface-mount, no-lead package: the pads are on the bottom, so the hot-air nozzle needs to heat the whole body evenly. A preheat plate at 150°C helps avoid thermal shock to the MEMS die. No direct replacement or successor has been announced; the DSC1123 series continues as the primary offering for this frequency and output type.","metaTitle":"DSC1123DI2-050.0000 Microchip MEMS XO, 50 MHz LVDS, ±25 ppm","metaDescription":"DSC1123DI2-050.0000: Microchip DSC1123 series MEMS XO, 50 MHz LVDS output, ±25 ppm stability, -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":"-","Function":"Enable/Disable","Frequency":"50 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 ~ 3.63V","Base Product Number":"DSC1123","Frequency Stability":"±25ppm","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":"$2.6700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32c33983bfd645bac8d0b2ac5207c872.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does the DSC1123DI2-050.0000 compare to a traditional quartz oscillator?","answer":"The MEMS resonator is inherently more resistant to vibration and shock than a quartz crystal — no quartz blank to crack or drift under mechanical stress. The ±25 ppm stability is comparable to a standard quartz XO, but the MEMS part typically starts up faster (sub-millisecond) and has a wider operating temperature range without the frequency dip quartz exhibits near its turnover point."},{"question":"What is the closest pin-compatible alternative in the DSC1123 family?","answer":"Any other DSC1123 part with the same 6-SMD, No Lead package and LVDS output is footprint-compatible — only the frequency and stability grade differ. For a direct drop-in at a different frequency, order the desired frequency with the same 'DI2' suffix (which encodes the package and stability).
