ECS-P85-A

Overview

The ECS-P85-A is a programmable crystal-controlled oscillator manufactured by ECS Inc. International, designed for general-purpose embedded systems requiring reliable clock accuracy. It operates at a nominal supply voltage of 5V and features an HCMOS output interface. The device supports frequency ranges from 1 MHz to 150 MHz with a total frequency stability of ±100ppm. It utilizes a half-size metal can package (8-DIP, 4 leads) measuring 13.20mm x 13.20mm. Key electrical characteristics include a maximum supply current of 45mA and an operating temperature range of 0°C to 70°C.

Feature Summary

• Programmable crystal-controlled design allowing flexible frequency configuration
• HCMOS output interface compatible with standard digital logic circuits
• Enable/Disable functionality for power management control
• Half-size metal can packaging suitable for space-constrained PCB layouts

Applications

• General-purpose embedded systems requiring precise clock signals
• Microcontroller clock sources in industrial control applications
• Digital signal processing equipment timing references
• Communication module synchronization circuits

Procurement Notes

Verify the specific frequency order code suffix when purchasing, as the base model ECS-P85-A requires a designated suffix to define the exact operating frequency within the 1-150 MHz range. Confirm that the 5V supply voltage requirement aligns with your system design, as this component is distinct from the 3.3V ECS-P83 series. Ensure compatibility with the 8-DIP half-size footprint during PCB layout finalization.

Selection Notes

Select the ECS-P85-A when a 5V operating voltage is required rather than the 3.3V alternative. Consider this component for applications needing programmable frequency generation within the specified range. Verify that the ±100ppm stability meets your system's timing requirements. Choose this part if the half-size DIP package fits your assembly constraints better than surface-mount options.

Part Context

The ECS-P85-A belongs to the ECS-P83/P85 family of programmable clock oscillators from ECS Inc. International. This family includes the 3.3V ECS-P83 variant and the 5V ECS-P85 variant. Both share similar programmable architecture and packaging but differ in supply voltage specifications. The P85 series is designed to replace fixed-frequency crystals in designs requiring flexibility or multiple frequency options.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout compatibility and electrical parameters before substituting with other programmable oscillators.
