ECS-P73-A

Overview

The ECS-P73-A is a programmable surface-mount HCMOS clock oscillator manufactured by ECS Inc. It operates on a single 3.3V supply and features an enable/disable function for power management. The device supports a frequency range from 1 MHz to 125 MHz with a total frequency stability of ±100ppm. It utilizes a 4-SMD, no-lead ceramic package measuring 7.0 x 5.0 mm. The component is designed for one-time programming and functions within an operating temperature range of -10°C to 70°C.

Feature Summary

• One-time programmable crystal-controlled operation
• HCMOS output signal compatibility
• Integrated enable and disable control function

Applications

• General purpose clock generation in embedded systems
• Timing reference for microprocessors and microcontrollers
• Digital communication interface synchronization

Procurement Notes

Verify the specific frequency order code against the manufacturer's official catalog, as the base model number requires a suffix for exact frequency specification. Confirm that the 3.3V supply voltage aligns with the target circuit design requirements. Ensure the SMD package dimensions are compatible with the PCB footprint and reflow soldering profile specifications provided in the datasheet.

Selection Notes

Select this component when a low-profile, programmable clock source is required for 3.3V logic systems. Consider the ±100ppm stability requirement against system timing tolerances. Evaluate the need for an enable pin if dynamic power saving is necessary. Compare the 7.0 x 5.0 mm package size against available board space constraints relative to other oscillator families.

Part Context

This part belongs to the ECS-P73 series of programmable SMD clock oscillators. It is distinct from the ECS-P75 series, which operates at 5V. The P73 series is characterized by its ceramic construction and one-time programmability, offering a compact solution for fixed-frequency applications where standard crystals would require additional external circuitry.

Replacement Considerations

Direct substitutes must match the 3.3V supply, HCMOS output, and 4-SMD package. Verify frequency availability and stability specifications before cross-referencing with other manufacturers' programmable oscillator lines.
