ECS-3518-250-B-TR Description

Short technical summary and product information.

The ECS-3518-250-B-TR is a 25 MHz XO (Standard) oscillator from ECS Inc. featuring HCMOS output logic. It operates with a nominal supply voltage of 1.8V (range 1.62V to 1.98V) and provides a frequency stability of ±50 ppm over the 0°C to 70°C operating temperature range.

 

This oscillator includes an Enable/Disable function for power management and offers typical rise and fall times of 5 ns with a 30 pF HCMOS load. The output symmetry is 40/60% at 50% VCC level. Startup time is typically 10 ms.

 

The device is housed in a compact 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a height of 1.30mm, suitable for surface mount assembly. It is supplied in tape and reel packaging with a standard quantity of 1000 pieces per reel.

 

Typical applications include clock generation for digital circuits, microcontrollers, and communication interfaces where a stable 25 MHz reference is required.
