Do not plan a new design around this order code. Rated AEC-Q100, this oscillator was qualified for automotive stress and reliability requirements. ## Key ratings for clock-tree fit 42 MHz fixed frequency with CMOS output drives MCU clock inputs, Ethernet PHY reference clocks, or FPGA PLLs directly — no external load capacitors needed, unlike a quartz crystal. Frequency stability of ±25 ppm keeps the clock edge within tight timing margins for 100BASE-T or USB full-speed interfaces. Supply voltage spans 1.71 V to 3.63 V, so the same part works on 1.8 V, 2.5 V, or 3.3 V rails without a level translator. ## Package and board layout note Housed in a 4-SMD, No Lead package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm. The small footprint suits space-constrained automotive modules.","metaTitle":"DSC6001HI2A-042.0000 MEMS XO 42 MHz CMOS AEC-Q100 Obsolete","metaDescription":"Microchip DSC6001HI2A-042.0000 MEMS oscillator, 42 MHz CMOS output, ±25 ppm stability, AEC-Q100, 1.71–3.63 V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC60XX","Package":"Bag","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"42 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.063\\\" L x 0.047\\\" W (1.60mm x 1.20mm)","Voltage - Supply":"1.71V ~ 3.63V","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.89mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"1.3mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f42caf3e07022c4d06d7c884f387c56e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for DSC6001HI2A-042.0000?","answer":"The DSC60XX series includes other frequencies and stability grades, but a direct drop-in at 42 MHz with the same AEC-Q100 rating is not listed.
