The enable/disable function (pin-controlled) allows the clock to be gated off in low-power standby states without a separate load switch. Current consumption maxes at 42 mA across the full frequency band, so the thermal rise in the plastic 6-SMD package stays within the derating envelope even at 85°C ambient. ## Blank-programmable — design-in workflow This part is shipped blank (unprogrammed), meaning the target frequency is written by the designer via Microchip's field-programmable MEMS oscillator programmer or pre-programmed by the distributor at order time. The blank (User Must Program) designation gives BOM flexibility: a single line item covers multiple frequency variants in prototype builds, and the final frequency is locked at the programming step.","metaTitle":"Microchip DSC8124BI2 MEMS XO, HCSL, 10-460 MHz, AEC-Q100","metaDescription":"DSC8124BI2 MEMS XO standard oscillator, HCSL output, 10 MHz to 460 MHz, ±25 ppm stability, AEC-Q100 qualified, -40°C to +85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"HCSL","Series":"DSC8124","Package":"Tube","Ratings":"AEC-Q100","Function":"Enable/Disable","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 ~ 3.6V","Programmable Type":"Blank (User Must Program)","Base Product Number":"DSC8124","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"42mA","Available Frequency Range":"10 MHz ~ 460 MHz","Spread Spectrum Bandwidth":"-","Frequency Stability (Total)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b114477e2ae1e9c8bbb9420182bdf8b9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the DSC8124BI2?","answer":"Within the DSC8124 series, any blank-programmable DSC8124 variant can be set to the same frequency and output type, but the exact AEC-Q100 rating and ±25 ppm stability are specific to this order code."},{"question":"What compliance documentation does Microchip provide for the DSC8124BI2?","answer":"Microchip provides RoHS and REACH compliance declarations for the DSC8124 series.
