The 32 mA max supply current (22 mA disabled) is a fixed overhead — no load-capacitance tuning or drive-level adjustment needed, unlike a quartz oscillator. ## AEC-Q100 qualification and package fit The 6-SMD, No Lead package (2.50 mm x 2.00 mm, 0.90 mm seated height) is a standard MEMS oscillator footprint; the board layout matches the common 6-pin ceramic or plastic package outline. ## MEMS vs quartz — what changes on the board A MEMS oscillator replaces the quartz crystal plus load capacitors and inverter with a single IC. The DSC1123DI2-187.5000T is a direct drop-in for a standard 6-pin LVDS oscillator footprint — no external feedback network or tuning capacitors. The ±25 ppm stability includes the MEMS resonator's aging and temperature drift, so the timing budget is set by the oscillator alone, not the board parasitics.","metaTitle":"DSC1123DI2-187.5000T – Microchip 187.5 MHz LVDS MEMS","metaDescription":"Active Microchip DSC1123DI2-187.5000T: 187.5 MHz LVDS XO, ±25 ppm, AEC-Q100, 2.25-3.63 V, 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":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"187.5 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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32c33983bfd645bac8d0b2ac5207c872.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the DSC1123DI2-187.5000T replace a quartz oscillator in my design?","answer":"Yes, if the board expects a 6-pin LVDS oscillator with Enable/Disable. The MEMS device does not require external load capacitors or a feedback resistor — the oscillator is self-contained. Verify the supply voltage range (2.25 V to 3.63 V) and the output type (LVDS) match your clock receiver. The ±25 ppm stability is comparable to a standard quartz XO."},{"question":"Is the DSC1123DI2-187.5000T compatible with a 2.5 V supply?","answer":"Yes. The supply voltage range is 2.25 V to 3.63 V, so 2.5 V is within the operating window. The oscillator's LVDS output swing scales with the supply, but the differential swing at 2.5 V still meets the LVDS receiver threshold — no level translation needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123DI2-187.5000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123DI2-187.5000T when reusing this data.
