This lets a single device drive a mixed-speed clock tree — for example, a 25 MHz MCU core clock alongside a 125 MHz Ethernet PHY reference — reducing component count and routing complexity on the board. ## Supply voltage flexibility and power-down control Operating from 2.25 V to 3.6 V, the part covers 2.5 V and 3.3 V logic rails without an external LDO. When disabled, the maximum supply current drops to 23 mA, which is the residual draw from the MEMS core and PLL. ## Package footprint and layout considerations The 6-VDFN package measures 2.50 mm x 2.00 mm with a 0.90 mm height. This compact footprint suits space-constrained designs like PCIe cards or small-form-factor modules. The 0.90 mm profile clears typical board-to-board stacking gaps. Standard FR-4 layout rules apply — place the decoupling cap within 2 mm of the supply pin, and keep the CMOS output trace short to minimise edge-rate ringing. It fits indoor equipment, office peripherals, networking gear, and consumer electronics. Not qualified for automotive (no AEC-Q100) or extended industrial ambient above 70°C. The base product number DSC2311 covers the series; confirm the specific frequency and stability variant when ordering.","metaTitle":"DSC2311KE1-R0002T MEMS XO – 25 MHz & 125 MHz CMOS, Active","metaDescription":"Microchip DSC2311KE1-R0002T dual-output MEMS oscillator: 25 MHz + 125 MHz CMOS, 2.25-3.6 V, ±50 ppm, -20°C to 70°C, Enable/Disable, 6-VDFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"CMOS","Series":"DSC2311","Package":"Tape & Reel (TR)","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"6-VDFN","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 ~ 3.6V","Base Product Number":"DSC2311","Frequency Stability":"±50ppm","Frequency - Output 1":"25MHz","Frequency - Output 2":"125MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-","Current - Supply (Disable) (Max)":"23 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a2c4354b9a6d37854053a5719c7dc321.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC2311KE1-R0002T a reliable replacement for a single-output 25 MHz crystal oscillator?","answer":"Yes, if your design needs a 25 MHz CMOS clock, the DSC2311KE1-R0002T can replace a standard 25 MHz XO — but note it also provides a second 125 MHz output. That second output may be unused or require a no-connect on the PCB. The MEMS resonator offers better shock resistance than quartz, which can improve reliability in portable or vibration-prone environments. No pin-compatible alternative is listed; the DSC2311 series is the direct family."},{"question":"Does the DSC2311KE1-R0002T have an enable/disable function?","answer":"Yes, the part includes an Enable/Disable function. When disabled, the maximum supply current is 23 mA — the MEMS core and PLL remain powered, but the CMOS outputs are tri-stated. This allows the system to gate the clock for power saving or test modes without removing the supply rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC2311KE1-R0002T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC2311KE1-R0002T when reusing this data.
