ECS-P143-ANX

Overview

The ECS-P143-ANX is a programmable crystal oscillator (XO) from the ECS-P143 series, manufactured by ECS Inc. It utilizes an HCMOS output interface and operates on a 3.3V supply voltage with a maximum current consumption of 28mA. The device supports a frequency range of 1 MHz to 125 MHz, programmed via distributor order notes. It features ±100ppm total frequency stability and includes enable/disable functionality. The component is housed in a 14-DIP package with four leads, specifically a full-size metal can configuration, designed for through-hole mounting.

Feature Summary

• Programmable frequency generation within a wide range using distributor programming services
• HCMOS logic output compatible with standard digital interfaces
• Integrated enable and disable control function for power management
• Robust full-size metal can packaging for environmental protection

Applications

• General-purpose clock signal generation for digital circuits
• Embedded systems requiring precise timing references
• Industrial equipment needing reliable oscillation sources
• Communication modules utilizing standard HCMOS interfaces

Procurement Notes

This component requires specific frequency programming during the ordering process. Buyers must input the desired frequency value into the website order remarks or notes field when placing orders through authorized distributors such as DigiKey. The part is currently listed as Last Time Buy status with a final purchase date in September 2026. Verification of the programming instructions and lead times is essential before finalizing procurement plans due to the custom nature of the frequency setting.

Selection Notes

Select this model when a programmable HCMOS oscillator is required with a 3.3V supply and through-hole mounting capability. The ±100ppm stability suits applications where moderate precision is acceptable. Ensure the design accommodates the 14-DIP full-size metal can dimensions. Compare against the ECS-P143-B variant if higher ±50ppm stability or commercial temperature range suffices. Verify that the distributor's programming service aligns with project timelines.

Part Context

The ECS-P143-ANX belongs to the ECS-P143X family of programmable clock oscillators. This series offers flexibility in frequency selection while maintaining standard electrical characteristics. The 'AN' suffix typically denotes the -40°C to 85°C industrial temperature range and 3.3V operation. The 'X' indicates tube packaging. This component serves as a customizable timing solution for designs transitioning from fixed-frequency crystals to flexible oscillator requirements.

Replacement Considerations

The ECS-P143-B is a verified substitute offering improved ±50ppm stability, though it operates within a 0°C to 70°C commercial temperature range rather than the industrial range of the ANX variant. Both share identical packaging, voltage, and output types. Designers must verify thermal requirements before substitution. No other direct cross-model replacements are documented in the provided data.
