ECS-P73-BN

Overview

The ECS-P73-BN is a programmable crystal oscillator manufactured by ECS Inc., designed for surface-mount applications. It features an HCMOS output signal and operates with a supply voltage of 3.3V. The device provides a frequency range from 1 MHz to 125 MHz with a total frequency stability of ±50ppm. It supports an operating temperature range of -40°C to 85°C and has a maximum supply current of 28mA. The component is housed in a compact 4-SMD, No Lead package measuring 7.00mm x 5.00mm.

Feature Summary

• Programmable frequency generation within the 1 MHz to 125 MHz range
• HCMOS output interface compatible with standard logic levels
• Wide industrial operating temperature range for environmental resilience

Applications

• General-purpose clock generation for digital circuits
• Embedded systems requiring precise timing references
• Communication equipment utilizing standard serial interfaces

Procurement Notes

Verify the specific frequency order code when purchasing, as the base model number may require suffixes for exact frequency selection. Confirm that the 3.3V supply requirement aligns with the target system design. Ensure the 4-SMD no-lead package dimensions fit the PCB footprint constraints. Check for any specific enable/disable pin configurations if power management is required in the application.

Selection Notes

Select this component when a fixed-frequency oscillator is insufficient and programmability is needed for production flexibility. The HCMOS output is suitable for most microprocessors and FPGAs. Consider the ±50ppm stability specification against the system's jitter tolerance requirements. The wide temperature range makes it appropriate for industrial or automotive environments where thermal variation is expected.

Part Context

The ECS-P73 series represents ECS Inc.'s line of surface-mount programmable oscillators. This family offers flexibility in frequency configuration while maintaining a small form factor. The P73 variant specifically targets applications requiring reliable clock sources with moderate stability. It competes with other SMD programmable oscillators offering similar voltage and output drive capabilities.

Replacement Considerations

Direct substitutes must match the 4-SMD no-lead package and 3.3V supply voltage. Verify compatibility of the HCMOS output swing with the receiving circuitry. Ensure the replacement part supports the same frequency range and stability specifications. Cross-reference pinouts to confirm functional equivalence without redesigning the PCB layout.
