ECS-P75-A

Overview

The ECS-P75-A is a programmable surface-mount crystal oscillator manufactured by ECS Inc. It operates at 5V with an HCMOS output interface and supports frequencies from 1 MHz to 150 MHz. The device features a frequency stability of ±100ppm over the operating temperature range of -10°C to 70°C. It draws a maximum supply current of 45mA and utilizes a compact 4-SMD, no-lead package for efficient board integration.

Feature Summary

• One-time programmable crystal-controlled operation
• HCMOS output signal compatibility
• Compact low-profile SMD ceramic package

Applications

• Consumer electronics clock generation
• Telecommunications system timing
• General-purpose digital circuit synchronization

Procurement Notes

Verify the specific programming requirements and frequency configuration before procurement. Ensure the 5V supply voltage matches the design specifications. Confirm the surface-mount footprint dimensions align with the PCB layout. Check RoHS compliance status if required by project standards. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this component when a fixed-frequency programmable oscillator is needed for 5V logic systems. Consider the ±100ppm stability requirement for timing accuracy. Evaluate the 45mA current consumption against power budget constraints. Ensure the 1 MHz to 150 MHz range covers the target application frequency needs.

Part Context

The ECS-P75-A belongs to the ECS-P73/P75 family of programmable SMD clock oscillators. While the P73 variant operates at 3.3V, the P75 series is designed for 5V applications. This family offers a cost-effective solution for integrating precise clock signals into space-constrained electronic designs without requiring external discrete components.

Replacement Considerations

Direct substitutes include other 5V programmable HCMOS oscillators with similar frequency ranges and package dimensions. Verify pinout compatibility and electrical parameters such as supply voltage and current draw. Cross-reference with manufacturer datasheets to ensure equivalent performance characteristics.
