EMRA33E2H-1.024M

Oscillators Overview

The EMRA33E2H-1.024M is a MEMS-based standard clock oscillator manufactured by Ecliptek, part of the EMRA33 series. It operates at a nominal frequency of 1.024MHz with a frequency tolerance of ±100ppm over an operating temperature range of -20°C to +70°C. The device utilizes LVCMOS output logic and requires a 3.3Vdc supply voltage. It is housed in a compact 2.5mm x 3.2mm surface-mount package with four pads.

Oscillators Feature Summary

• MEMS technology for enhanced reliability compared to traditional quartz oscillators
• LVCMOS output interface compatible with standard digital logic levels
• Compact surface-mount design suitable for space-constrained applications

Oscillators Applications

• General-purpose timing reference for embedded systems
• Clock source for microcontrollers and DSPs
• Industrial control equipment requiring stable low-frequency timing

Oscillators Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm that the specified operating temperature range (-20°C to +70°C) aligns with the target application environment. Ensure supply chain stability as this component may be subject to discontinuation notices from the manufacturer.

Oscillators Selection Notes

Select this model when a low-cost, reliable MEMS oscillator is required for frequencies around 1MHz. Consider the ±100ppm stability specification against system jitter requirements. Verify that the 3.3V supply voltage matches the target circuit's power domain and that the LVCMOS output swing is compatible with downstream logic inputs.

Oscillators Part Context

This component belongs to the EMRA33 series of programmable MEMS oscillators from Ecliptek. The series offers various frequency options within a standardized 2.5mm x 3.2mm footprint. This specific variant provides a 1.024MHz output, commonly used in telecommunications and audio processing applications requiring precise sub-MHz timing references.

Oscillators Replacement Considerations

Direct substitutes include other MEMS oscillators from Ecliptek or Abracon within the same EMRA33 family offering identical 1.024MHz frequency and similar package dimensions. Cross-vendor replacements must match the LVCMOS output type, 3.3V supply requirement, and -20°C to +70°C temperature range.
