ECS-P143-AX

Overview

The ECS-P143-AX is a programmable crystal oscillator manufactured by ECS Inc., designed for through-hole mounting in a full-size 14-DIP metal can package. It operates on a 3.3V supply voltage with a maximum current consumption of 28mA. The device features HCMOS output signals and includes an enable/disable function for power management. It supports a frequency range from 1 MHz to 125 MHz, programmed via DigiKey order notes. The unit offers a total frequency stability of ±100ppm and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Programmable frequency generation capability allowing custom clock frequencies within the specified range.
• HCMOS output interface compatible with standard digital logic circuits.
• Integrated enable/disable control functionality for system power optimization.

Applications

• General-purpose clock signal generation for embedded systems
• Timing reference sources for microcontroller-based designs
• Industrial equipment requiring stable programmable clock inputs

Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 3.3V supply requirement and ±100ppm stability. Confirm that the 14-DIP through-hole package fits the target PCB layout. Ensure the programming process via distributor order notes is understood prior to purchase, as the frequency is not fixed at manufacturing.

Selection Notes

Select this component when a programmable HCMOS oscillator is required in a full-size DIP package. It is suitable for applications needing 3.3V operation and moderate frequency stability. Consider the ECS-P143-B if higher stability (±50ppm) or 5V operation is needed, or the ECS-P143-AN for extended temperature ranges.

Part Context

This component belongs to the ECS-P143X series of programmable oscillators. It shares the same physical footprint and basic interface characteristics with other variants in the series, differing primarily in voltage, stability, and temperature ratings. The series is designed to provide flexible timing solutions for various electronic applications.

Replacement Considerations

Direct substitutes include ECS-P143-B for improved stability or ECS-P143-AN for wider temperature tolerance. Verify pin compatibility and voltage levels before substitution. No other direct cross-model replacements are confirmed in public documentation.
