ECS-P73-B

Overview

The ECS-P73-B is a programmable surface-mount HCMOS clock oscillator manufactured by ECS Inc. It operates within a frequency range of 1 MHz to 125 MHz and provides a total frequency stability of ±50ppm. The device requires a 3.3V supply voltage and draws a maximum current of 28mA. It supports Enable/Disable functionality and functions reliably across an operating temperature range of -10°C to 70°C.

Feature Summary

• Programmable frequency generation capability within the specified range
• HCMOS output signal compatibility for digital logic interfaces
• Integrated enable and disable control function

Applications

• General purpose clock signal generation in embedded systems
• Timing reference sources for microprocessors and FPGAs
• Industrial control equipment requiring stable clock inputs

Procurement Notes

Verify that the specific order matches the exact part number ECS-P73-B, as the base series allows for various frequency configurations. Confirm that the required operating temperature range aligns with the -10°C to 70°C specification. Ensure the system design accommodates the 3.3V supply requirement and the maximum 28mA current draw. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a programmable HCMOS oscillator is required for frequencies between 1 MHz and 125 MHz. Consider the ±50ppm stability limit against system timing requirements. Evaluate the -10°C to 70°C industrial temperature range suitability for the deployment environment. Verify that the 4-SMD no-lead package fits the PCB layout constraints and that the 3.3V logic level matches the receiving circuitry.

Part Context

This component belongs to the ECS-P73 series of programmable SMD clock oscillators from ECS Inc. The series offers flexible frequency options ranging from 1 MHz to 125 MHz. It utilizes standard HCMOS outputs and supports surface-mount assembly. The family includes variants with different suffixes indicating specific frequencies or packaging details.

Replacement Considerations

Direct substitutes must match the 4-SMD no-lead package, 3.3V supply, and HCMOS output type. Verify equivalent frequency stability of ±50ppm and compatible operating temperature ranges. Cross-reference pinouts and electrical characteristics carefully before integration.
