ECS-P55-B

Overview

The ECS-P55-B is a programmable surface-mount crystal oscillator manufactured by ECS Inc. It operates on a 5V supply and delivers an HCMOS output signal. The device supports frequency stability of ±50ppm across a commercial operating temperature range of 0°C to 70°C. Maximum supply current is rated at 50mA. The component utilizes a compact 4-pin SMD package with no lead, designed for space-constrained applications requiring precise clock generation.

Feature Summary

• Programmable frequency configuration within the specified operational range
• Compact sub-minimum profile package design suitable for high-density mounting
• HCMOS output interface compatible with standard digital logic circuits

Applications

• General purpose clock generation in embedded systems
• Timing reference for microprocessors and microcontrollers
• Data communication equipment requiring stable clock signals

Procurement Notes

Verify the specific frequency variant required, as the base model designation covers a range of frequencies. Confirm that the 5V supply voltage aligns with the target circuit design. Ensure the commercial temperature range meets environmental requirements. Check for any specific ordering suffixes that may indicate pinout or tolerance variations. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this component when a 5V supply is available and HCMOS output levels are required. Consider the ±50ppm stability requirement against system timing constraints. Evaluate the physical dimensions of the 4-SMD package against board space limitations. Compare against lower voltage alternatives if power consumption is a critical factor. Ensure the operating temperature range suits the intended deployment environment.
