ECS-P143-A

Overview

The ECS-P143-A is a programmable crystal oscillator (XO) manufactured by ECS Inc., designed for through-hole mounting in a 14-DIP, 4-lead full-size metal can package. It operates on a 3.3V supply voltage and features an HCMOS output signal. The device supports a frequency range from 1 MHz to 125 MHz with a total frequency stability of ±100ppm. Maximum supply current is specified at 45mA. It includes enable/disable functionality and is programmed by Digi-Key upon order.

Feature Summary

• Programmable frequency generation within the 1 MHz to 125 MHz range via external ordering specifications.
• HCMOS logic output compatible with standard digital interfaces.
• Hardware control capability for enabling or disabling the oscillator output signal.
• Robust construction utilizing a full-size metal can package for environmental protection.

Applications

• General-purpose clock source generation for digital circuits
• System timing reference in industrial control equipment
• Embedded systems requiring precise frequency customization

Procurement Notes

This component requires specific programming parameters to be provided during the ordering process. Customers must input the desired frequency into the website order notes when purchasing through authorized distributors like Digi-Key. Verification of the exact frequency requirement prior to submission is essential, as the unit is customized per order. Ensure that the 3.3V supply voltage and HCMOS output levels align with the target system design specifications before finalizing procurement.

Selection Notes

Select the ECS-P143-A when a customizable clock frequency between 1 MHz and 125 MHz is required with high reliability. This model is suitable for applications needing a metal-can packaged oscillator with HCMOS outputs and 3.3V operation. Consider the ±100ppm total frequency stability and 45mA maximum current consumption against system power budgets. Verify that the through-hole 14-DIP form factor fits the PCB layout constraints compared to surface-mount alternatives.

Part Context

The ECS-P143-A belongs to the ECS-P143 series of programmable oscillators from ECS Inc. This series offers customizable frequencies for various digital applications. Unlike fixed-frequency crystals, these units are programmed after order placement. The P143-A specifically denotes the 3.3V variant with HCMOS outputs, distinguishing it from other voltage or output type variations within the broader programmable oscillator family.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 3.3V supply, HCMOS output, 14-DIP metal can package, and programmable frequency range. Consult manufacturer documentation for potential obsolescence notices or series updates.
