ECS-2520S33-400-FN-TR standard XO, 40 MHz HCMOS, 3.3V, ±10ppm, Enable/Disable, 4-SMD 2.50mm x 2.00mm, -40°C~85°C, Tape & Reel.","salesMarkdown":"## 40 MHz HCMOS clock with ±10ppm stability The ECS-2520S33-400-FN-TR: Its ±10ppm frequency stability covers the tight tolerance window required for communication ports, timing references, and ADC/DAC clock trees where a wandering reference eats into dynamic range. The base resonator is a quartz crystal, which means the output phase-noise floor and close-in 1/f behavior are set by the resonator Q — a crystal-based XO generally outperforms a MEMS oscillator in the 1 kHz to 100 kHz offset region where switching supplies and load transients typically land. Listed as Active by ECS Inc. — ordered to BOM quantity through independent distribution, with availability and current lead times confirmed at RFQ.","metaTitle":"ECS-2520S33-400-FN-TR, 40 MHz XO HCMOS ±10ppm 3.3V","metaDescription":"ECS Inc.
