These frequencies are the standard audio sample-rate references — 45.1584 MHz serves 44.1 kHz-family audio (CD, DAT), while 49.152 MHz covers 48 kHz-family audio (AES/EBU, Dolby Digital) and common video pixel clocks. A single oscillator replaces two cans on the board, saving footprint and BOM line count. ## Supply range, stability, and enable function Operates from a wide 2.25 V to 3.6 V supply rail, covering 2.5 V and 3.3 V logic domains without an extra regulator. ## Package, footprint, and sourcing posture Housed in a 20-VFQFN exposed-pad package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm.","metaTitle":"DSC400-0101Q0083KE2T MEMS XO – 45.1584/49.152 MHz LVCMOS","metaDescription":"Microchip DSC400-0101Q0083KE2T MEMS XO, dual LVCMOS outputs at 45.1584 MHz and 49.152 MHz, ±25 ppm stability, 2.25-3.6 V supply, -20 to +70 °C, 20-VFQFN.","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":"LVCMOS","Series":"DSC400","Package":"Tape & Reel (TR)","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"20-VFQFN Exposed Pad","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":"DSC400","Frequency Stability":"±25ppm","Frequency - Output 1":"45.1584MHz","Frequency - Output 2":"-","Frequency - Output 3":"49.152MHz","Frequency - Output 4":"-","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b1fa89bbb593bb9f15bbf883a84023ea.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC400-0101Q0083KE2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC400-0101Q0083KE2T when reusing this data.
