The 4-VFLGA package (1.60 mm x 1.20 mm footprint, 0.89 mm seated height) fits tight PCB layouts where a larger can oscillator would not clear the enclosure wall. ## Supply voltage range and frequency stability The 1.8V–3.3V supply range lets this oscillator serve as a single clock source across mixed-voltage domains — a 1.8V MCU core and a 3.3V peripheral bus can share the same reference without a level translator on the clock line. The ±20 ppm absolute pull range sets the frequency stability budget. For a 27 MHz reference driving a USB or Ethernet PHY, ±20 ppm keeps the bit-rate error within the receiver's tolerance window over the full temperature range. ## Enable/Disable function for power gating Instead of a separate load switch on the supply rail, the oscillator itself stops drawing current when disabled — a clean way to cut clock power without adding a MOSFET.","metaTitle":"DSC6003HI3B-027.0000 MEMS XO – 27 MHz, AEC-Q100, 1.8V–3.3V","metaDescription":"Microchip DSC6003HI3B-027.0000: 27 MHz MEMS oscillator, AEC-Q100 qualified, 1.8V–3.3V supply, CMOS output, Enable/Disable, 4-VFLGA 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":"DSC60XXB","Package":"Bag","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"27 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-VFLGA","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.063\\\" L x 0.047\\\" W (1.60mm x 1.20mm)","Voltage - Supply":"1.8V ~ 3.3V","Base Product Number":"DSC6003","Frequency Stability":"-","Height - Seated (Max)":"0.035\\\" (0.89mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"1.3mA (Typ)","Absolute Pull Range (APR)":"±20ppm","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fc9bc8dbecf8bce854cdcb4e33a6ea8e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC6003HI3B-027.0000 AEC-Q100 qualified?","answer":"Yes, the DSC6003HI3B-027.0000 carries AEC-Q100 qualification. This means it has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and is suitable for under-hood or cabin ECUs operating in the -40°C to 85°C range."},{"question":"What is the output type and package of DSC6003HI3B-027.0000?","answer":"Output is CMOS.
