This eliminates a second oscillator footprint and the associated routing complexity. That stability holds without external load capacitors — the MEMS resonator and PLL are self-contained. Supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails. ## Package and board-fit notes for the 6-VDFN Housed in a 6-VDFN measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The MEMS die eliminates the quartz crystal's mechanical resonance — no startup reliability concerns from shock or vibration. The Enable/Disable pin allows the oscillator to be tri-stated for system test or power sequencing. Lifecycle status is Active — no EOL, no NRND notice. Microchip lists no direct pin-compatible second source, but the DSC2311 family includes multiple frequency and stability variants sharing the same 6-VDFN footprint.","metaTitle":"DSC2311KL2-R0040 MEMS XO – 40/20 MHz, ±25 ppm","metaDescription":"Active Microchip DSC2311KL2-R0040 dual-output MEMS oscillator: 40 MHz + 20 MHz CMOS, ±25 ppm stability, 2.25-3.6 V supply, 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":"Tube","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":"±25ppm","Frequency - Output 1":"40MHz","Frequency - Output 2":"20MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C ~ 105°C","Current - Supply (Max)":"-","Current - Supply (Disable) (Max)":"23 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/013f3bc253e72b0f477ddc4fc68cf600.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order DSC2311KL2-R0040 or request a quote?","answer":"This active Microchip part is quoted to order against your BOM quantity.
