The MEMS resonator replaces a quartz crystal, giving faster start-up and better shock/vibration immunity than a traditional oscillator – useful in motor-drive and outdoor telecom enclosures where mechanical stress is present. The Enable/Disable function lets the system logic gate the outputs independently, pulling the disable current to 23 mA max – a power-saving feature for multi-rail boards that idle one clock domain. ## Supply voltage and temperature grade for BOM planning The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails without a separate regulator – one less line item on the BOM. Frequency stability is ±25 ppm across the full temperature and voltage range, tight enough for 100BASE-TX Ethernet and most serial protocols without external tuning components. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC2311KI2-R0020 MEMS XO – 164 MHz CMOS, ±25 ppm","metaDescription":"Microchip DSC2311KI2-R0020 XO (Standard) with MEMS resonator, dual 164 MHz CMOS outputs, ±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)","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":"164MHz","Frequency - Output 2":"164MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C~85°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":"What is the output frequency of DSC2311KI2-R0020?","answer":"Both outputs are 164 MHz CMOS.
