ECS-P145-A

Overview

The ECS-P145-A is a programmable crystal oscillator manufactured by ECS Inc. It operates at a supply voltage of 5V and features HCMOS output signals. The device supports a frequency range from 1MHz to 150MHz with a total frequency stability of ±100ppm. It is designed for an operating temperature range of 0°C to 70°C and has a maximum supply current of 45mA. The component utilizes a 14-DIP package with four leads.

Feature Summary

• Programmable clock oscillator functionality allowing custom frequency configuration
• HCMOS output signal compatibility for digital logic interfaces
• Tri-state control capability for output enable or disable operations

Applications

• General purpose clock generation in embedded systems
• Timing reference sources for microprocessor-based circuits
• Synchronization modules in industrial control equipment

Procurement Notes

Verify the specific frequency requirement during ordering as this model requires programming. Confirm that the 5V supply voltage aligns with system power rails. Ensure the 14-DIP package footprint matches the PCB design constraints. Check that the ±100ppm stability meets the application timing tolerance requirements before finalizing procurement.

Selection Notes

Select this component when a 5V HCMOS compatible clock source is required. Consider the ±100ppm stability specification against system jitter requirements. Verify the 0°C to 70°C operating range suits the environmental conditions. Ensure the programmable nature fits the production volume and customization needs compared to fixed-frequency alternatives.

Part Context

This part belongs to the ECS P143/P145 family of programmable oscillators. It shares the same 14-pin DIP form factor as related models like the ECS-P143. The series offers flexibility through frequency programming, distinguishing it from standard fixed-frequency crystals. It serves as a direct replacement for generic programmable XO applications requiring robust DIP packaging.

Replacement Considerations

The ECS-P145-ANX is a documented variant within the same product line. It offers extended temperature performance ranging from -40°C to 85°C while maintaining similar electrical characteristics. Substitution should verify thermal requirements and ensure pinout compatibility remains consistent across the family.
