The Enable/Disable pin further sharpens this advantage in systems that gate clocks to save power during low-power or standby states. ## ±10 ppm stability across the industrial thermal band Frequency stability of ±10 ppm at 27 MHz translates to a maximum deviation of ±270 Hz across the operating range — tight enough for UART clocking, SPI timing, and USB fractional-N synthesis without requiring software compensation. The -40 °C to 105 °C grade places this squarely in the industrial and light automotive temperature envelope; a design targeting under-hood or factory-floor environments stays within the ±10 ppm band without additional thermal management. Compare this against a ±20 ppm or ±50 ppm XO, where the accumulated timing error on a 1 ppm-synthesis UART clock demands a more forgiving baud-rate tolerance or a firmware trim table. ## Board footprint and disable-current sanity check Maximum supply current is 10 mA, which sets the minimum decoupling capacitance at the VCO rail — a single 100 nF ceramic placed close to the supply pin handles the high-frequency switching transient of the HCMOS output stage. In disable mode the oscillator draws a maximum of 10 µA, confirming it is safe to leave the supply rail active on µC boards that enter deep-sleep and gate the Enable line rather than remove power entirely.","metaTitle":"ECS-2520SMV-270-FP-TR, 27 MHz HCMOS XO, 1.62–3.63 V","metaDescription":"ECS-2520SMV-270-FP-TR is an Active 27 MHz HCMOS XO oscillator rated ±10 ppm from -40 to 105 °C, 1.62–3.63 V MultiVolt supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"ECS Inc.","Type":"XO (Standard)","Output":"HCMOS","Series":"ECS-2520SMV MultiVolt™","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Function":"Enable/Disable","Frequency":"27 MHz","Mounting Type":"Surface Mount","Base Resonator":"Crystal","Package / Case":"4-SMD, No Lead","Product Status":"Active","lifecycle_stage":"unknown","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"1.62V ~ 3.63V","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C ~ 105°C","Current - Supply (Max)":"10mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"10µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e61d8e6f2a112e939c4aa0ce36bbafa5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ECS-2520SMV-270-FP-TR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/ecs-inc/ECS-2520SMV-270-FP-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/ecs-inc/ECS-2520SMV-270-FP-TR when reusing this data.
