ECS-P143-BNX

Overview

The ECS-P143-BNX is a programmable crystal oscillator (XO) manufactured by ECS Inc. It utilizes HCMOS output signals and operates on a single 3.3V supply voltage. The device supports frequency selection ranging from 1 MHz to 125 MHz with a total frequency stability of ±50ppm. It features an enable/disable function and is housed in a 14-DIP package with four leads, specifically a full-size metal can configuration. The unit is designed for through-hole mounting and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Programmable frequency generation capability across a wide spectrum
• HCMOS logic output interface for digital circuit integration
• Integrated enable and disable control functionality
• Robust metal can packaging for environmental protection

Applications

• General purpose clock signal generation in embedded systems
• Timing reference sources for microcontroller-based designs
• Digital communication equipment requiring stable clock inputs
• Industrial control systems operating in varied thermal environments

Procurement Notes

Verify the specific frequency requirement during the ordering process, as this component requires programming to the desired operational speed. Confirm that the 3.3V supply voltage aligns with the target system design. Ensure the 14-DIP through-hole package dimensions fit the intended PCB layout. Check RoHS compliance status against project specifications, noting variations between manufacturing batches or revisions.

Selection Notes

Select this model when a flexible frequency solution is needed without custom hardware development. The ±50ppm stability offers precision suitable for most standard digital interfaces. Consider the enable/disable feature if power management during idle states is required. The metal can package provides superior shielding compared to plastic alternatives, making it suitable for noise-sensitive applications.

Part Context

This component belongs to the ECS-P143 series of programmable oscillators. It serves as a direct replacement for fixed-frequency crystals where variable timing is necessary. The series is widely used in legacy and modern electronics requiring reliable clock sources. The BNX suffix typically denotes specific manufacturing or compliance attributes distinct from the base P143-AN model.

Replacement Considerations

The ECS-P143-AN is a related variant within the same series but may differ in frequency stability specifications and supply voltage requirements. Verify compatibility regarding the ±100ppm versus ±50ppm tolerance before substitution. Ensure the pinout remains identical for direct board replacement.
