Total frequency stability is ±20 ppm over the full operating range — tight enough for CAN, FlexRay, and most SerDes reference clocks without external trimming. The part ships as a blank device (User Must Program), so you configure the output frequency during your production flow using Microchip's programming tools or a pre-programmed service. ## Package, footprint, and standby function Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator uses a standard surface-mount footprint that reflows without special stencil adjustments. The 6-lead VDFN is common for MEMS oscillators; the centre pad provides thermal relief and mechanical stability. A standby (power-down) function lets the oscillator drop to near-zero quiescent current when the enable pin is de-asserted — useful for battery-backed or ignition-switched modules that need to wake on a bus event.","metaTitle":"DSC1201BA3-PROGT MEMS Programmable XO – AEC-Q100","metaDescription":"DSC1201BA3-PROGT from Microchip Technology: MEMS-based XO, CMOS output, blank-programmable, 2.25–3.63 V, -40°C to 125°C, AEC-Q100, ±20 ppm stability.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC12X1","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","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","Programmable Type":"Blank (User Must Program)","Base Product Number":"DSC1201","Frequency Stability":"-","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~125°C","Current - Supply (Max)":"27mA (Typ)","Available Frequency Range":"2.5 MHz ~ 170 MHz","Spread Spectrum Bandwidth":"-","Frequency Stability (Total)":"±20ppm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/defa2245bd30f2f9faedadb454d26333.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How do I program the DSC1201BA3-PROGT blank oscillator?","answer":"You program the output frequency using Microchip's TimeFlash field programmer or their factory pre-programming service.

It uses a MEMS resonator instead of quartz, which offers better shock and vibration tolerance and faster startup. The 6-VDFN footprint matches common oscillator pads; verify the enable/standby pin mapping against your existing XO before committing."},{"question":"Is the DSC1201BA3-PROGT AEC-Q100 qualified?","answer":"Yes, the DSC1201BA3-PROGT carries AEC-Q100 qualification, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1201BA3-PROGT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1201BA3-PROGT when reusing this data.
