ECS-P73-AN

Overview

The ECS-P73-AN is a one-time programmable, crystal-controlled surface-mount clock oscillator manufactured by ECS Inc. It operates at a nominal frequency of 50 MHz with an HCMOS output interface. The device utilizes a 4-SMD, no-lead ceramic package measuring 7.0 x 5.0 mm. It functions on a 3.3V supply voltage and includes an enable/disable control feature. The unit offers frequency stability options of ±50 ppm or ±100 ppm within the operational range of 1 MHz to 125 MHz.

Feature Summary

• One-time programmable crystal-controlled oscillator design
• HCMOS output signal compatibility
• Integrated enable and disable control functionality
• Low-profile SMD ceramic package construction

Applications

• General purpose clock generation for digital circuits
• Embedded system timing references
• Communication equipment synchronization
• Microcontroller clock sources

Procurement Notes

Verify the specific suffix designation against the manufacturer's current documentation to ensure accurate configuration matching. Confirm that the one-time programming requirements align with your production workflow before procurement. Ensure the selected variant meets the required frequency tolerance and supply voltage specifications for the target application environment.

Selection Notes

Select this component when a fixed-frequency, low-profile clock source is required for space-constrained designs. The 3.3V operating voltage makes it suitable for modern logic families. Consider the ±50 ppm or ±100 ppm stability options based on the precision needs of the connected circuitry. Verify package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the ECS-P73 series of programmable oscillators from ECS Inc. The series features a 7.0 x 5.0 mm ceramic package designed for surface-mount assembly. The P73 variant specifically supports 3.3V operation, distinguishing it from the 5V P75 series. These devices are engineered as direct replacements for standard XO components in compact electronic assemblies.

Replacement Considerations

Direct substitutes include other models within the ECS-P73 family that match the 50 MHz frequency and 3.3V supply. Cross-reference pinout and package dimensions with alternative manufacturers' offerings if sourcing changes are necessary. Ensure compatible output drive strength and stability ratings.
