The MEMS resonator gives this oscillator better shock and vibration tolerance than a quartz crystal, which matters if the board sees portable or industrial handling. ## Standby power-down and commercial temperature grade A Standby (Power Down) function drops the supply current to 95 µA max when the enable pin is pulled low — useful for battery-powered equipment that sleeps between active bursts. Rated for -20°C to 70°C, this is a commercial-temperature part suited to indoor electronics, office equipment, and appliance PCBs where the ambient stays within that band.","metaTitle":"DSC1101CE5-045.1854 – 45.1854 MHz MEMS XO, CMOS, 2.25-3.6V","metaDescription":"Microchip DSC1101CE5-045.1854: 45.1854 MHz MEMS oscillator, CMOS output, 2.25-3.6V supply, -20°C to 70°C, 6-VDFN package.","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":"DSC1101","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"45.1854 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1101","Frequency Stability":"-","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"±10ppm","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"95µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I use the DSC1101CE5-045.1854 as a replacement for the DSC1101CE3-045.1854?","answer":"The DSC1101CE5 and DSC1101CE3 share the same base product number and 6-VDFN package, but the suffix indicates different temperature grades or options.
