The enable/disable function lets a downstream MCU gate the clock — pulling the pin low drops supply current from 35 mA max to 22 mA max, useful in sleep-mode power budgets.","metaTitle":"DSC1121BI2-050.0000T – Microchip MEMS XO, 50 MHz, AEC-Q100","metaDescription":"Microchip DSC1121BI2-050.0000T: 50 MHz MEMS oscillator, CMOS output, ±25 ppm stability, AEC-Q100 qualified.","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":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"50 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-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":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$56.2542","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1121BI2-050.0000T/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC1121BI2-050.0000T AEC-Q100 qualified?","answer":"Yes."},{"question":"Does the DSC1121BI2-050.0000T have an enable/disable function?","answer":"Yes. The enable/disable pin allows the output to be tri-stated.
