Product details

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.
