The 4-SMD no-lead package (5.00mm x 3.20mm footprint, 0.90mm seated height) fits standard oscillator land patterns — no layout change from a quartz XO of the same size. ## Power budget and standby behaviour Typical supply current is 4 mA while oscillating — the 1.8V rail sees roughly 7.2 mW load from the oscillator alone. When the Standby (Power Down) pin is asserted, the oscillator draws 1 µA maximum, cutting the clock tree's idle power to near-zero. A battery-powered sensor that sleeps 99% of the time and wakes to a 50 MHz host MCU can leave the oscillator enabled only during the active window, saving the 4 mA draw across the sleep interval.","metaTitle":"DSC1018BE1-050.0000 MEMS XO, 50 MHz CMOS, Active – Microchip","metaDescription":"DSC1018BE1-050.0000: MEMS-based XO, 50 MHz, CMOS output, 4 mA typ, 1 µA standby, -20°C to 70°C, active production.","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":"DSC1018","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"50 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-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":"1.8V","Base Product Number":"DSC1018","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"4mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0291cd7293e82768a7c2198660ff52d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the DSC1018BE1-050.0000 have a standby power-down feature?","answer":"Yes.
