ECS-P143-B

Overview

The ECS-P143-B is a programmable crystal oscillator (XO) 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 with a maximum current consumption of 28mA. The device supports a frequency range from 1 MHz to 125 MHz and maintains a total frequency stability of ±50ppm across an operating temperature range of 0°C to 70°C. It features HCMOS output logic and includes enable/disable functionality.

Feature Summary

• Programmable frequency generation within the 1 MHz to 125 MHz range using crystal control
• HCMOS output signal compatibility for digital circuit integration
• Enable/Disable control capability for power management
• Full-size 14-DIP metal can construction for robust physical protection

Applications

• General-purpose clock signal generation for digital systems
• Embedded controller timing references
• Industrial equipment requiring stable HCMOS clock sources
• Prototyping boards utilizing standard DIP footprints

Procurement Notes

Verify that the specific order notes explicitly state the required frequency, as this component is programmed by Digi-Key upon request. Confirm that the 3.3V supply voltage aligns with the target system design. Ensure the 14-DIP through-hole package fits the PCB layout constraints. Check RoHS status compliance if required by project specifications, noting this item may not be RoHS compliant.

Selection Notes

Select this model when a fixed-frequency crystal oscillator is needed but the exact frequency is determined post-manufacturing. It is suitable for designs requiring 3.3V operation and HCMOS outputs. Consider the ECS-P145 series if a 5V supply is preferred instead. Ensure the application environment stays within the 0°C to 70°C operational temperature range for specified stability.

Part Context

This part belongs to the ECS-P143 series of programmable clock oscillators. It shares the same 14-pin DIP footprint and mechanical dimensions as the ECS-P145 series, differing primarily in supply voltage requirements. The series is designed for applications needing precise timing without custom mask programming, offering flexibility through customer-specified frequency ordering.

Replacement Considerations

The ECS-P145-B serves as a functional substitute within the same family, offering identical packaging and features but requires a 5V supply voltage instead of 3.3V. Verify voltage compatibility before substitution. No other direct cross-model replacements are documented in official sources.
