Output is CMOS, so it drives logic inputs directly without external termination or level translation for most 1.8V to 3.3V rails. ## Automotive-grade timing for harsh environments Frequency stability is held to ±10 ppm across temperature, which keeps CAN, LIN, or Ethernet PHY clocking within the jitter budget without an external PLL cleanup. ## Standby function cuts power to 15 µA A standby (power-down) pin disables the output and drops supply current from 6.3 mA max to 15 µA max — useful for battery-backed modules that need to hold the clock tree off during sleep.","metaTitle":"DSC1001BL5-018.4320T MEMS XO – 18.432 MHz, AEC-Q100, CMOS","metaDescription":"Microchip DSC1001BL5-018.4320T: 18.432 MHz MEMS oscillator, CMOS output, ±10 ppm stability, 1.8V–3.3V supply, AEC-Q100 qualified, -40°C to 105°C.","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":"DSC1001","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"18.432 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 ~ 3.3V","Base Product Number":"DSC1001","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~105°C","Current - Supply (Max)":"6.3mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1001BL5-018.4320T AEC-Q100 qualified?","answer":"Yes, it is rated AEC-Q100, which qualifies it for automotive applications including under-hood and cabin environments."},{"question":"Can DSC1001BL5-018.4320T replace a standard 18.432 MHz crystal oscillator?","answer":"Yes, it is a drop-in MEMS replacement for a standard 18.432 MHz XO in a 4-SMD no-lead package, with CMOS output and a wide supply range — no board layout change needed."},{"question":"Does DSC1001BL5-018.4320T have an enable/standby function?","answer":"Yes, it has a standby (power-down) function that disables the output and reduces supply current to 15 µA max."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BL5-018.4320T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BL5-018.4320T when reusing this data.
