Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.50 mm pitch on the outer rows fans out on a two-layer board without via-in-pad; a four-layer board adds a ground plane under the part for EMI containment on the CMOS edge rates. The DSC1121 series is the current production family; no successor has been announced. The 6-SMD MEMS oscillator footprint is shared across the DSC1121 family, so a frequency change within the series keeps the same land pattern.","metaTitle":"DSC1121BM2-016.0000 MEMS XO – 16 MHz, CMOS, ±25 ppm","metaDescription":"Active Microchip Technology DSC1121BM2-016.0000 MEMS oscillator: 16 MHz, CMOS output, ±25 ppm stability, 2.25V–3.6V supply.","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":"DSC1121","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Frequency":"16 MHz","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","Base Product Number":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-55°C~125°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1121BM2-016.0000/alternatives.json"},"ai":{"faq":[{"question":"Can the DSC1121BM2-016.0000 replace a standard quartz oscillator?","answer":"Yes — the DSC1121BM2-016.0000 is a drop-in replacement for a 16 MHz quartz XO with CMOS output, provided the board layout is a 6-SMD no-lead footprint. The MEMS resonator offers better shock resistance and wider temperature range than most quartz parts, but the output drive strength and rise time are similar. Verify the Enable/Disable polarity matches your existing circuit; the DSC1121 uses a logic-high enable."},{"question":"What is the closest pin-compatible alternative in the DSC1121 family?","answer":"Any DSC1121BM2-xxx.xxxx with the same 6-SMD package and 2.25 V–3.6 V supply is pin-compatible.
