EMK43H2J-50.000M TR

Oscillators Overview

The EMK43H2J-50.000M TR is a MEMS clock oscillator manufactured by Ecliptek, designed for surface mount applications. It operates at a nominal frequency of 50.000 MHz with a maximum frequency stability of ±25 ppm over the industrial temperature range of -40°C to +85°C. The device utilizes LVCMOS output logic and requires a 3.3Vdc supply voltage. It features a compact 4-pad plastic SMD package measuring 2.0mm x 2.5mm. The component supports an enable/disable function for power management and includes tri-state capabilities. It is RoHS compliant and lead-free.

Oscillators Feature Summary

• MEMS technology ensures high reliability and shock resistance compared to traditional crystal oscillators.
• Integrated enable/disable control allows for active power management in battery-operated systems.
• Compact 4-pin surface mount footprint facilitates automated assembly and space-constrained designs.

Oscillators Applications

• Industrial communication modules requiring precise timing signals
• Embedded computing systems utilizing LVCMOS interfaces
• Portable electronic devices necessitating low-power standby modes

Oscillators Procurement Notes

Verify that the specific suffix 'TR' corresponds to tape and reel packaging requirements for your manufacturing line. Confirm that the ±25 ppm stability specification meets the system's jitter and phase noise budget. Ensure the PCB land pattern matches the 2.0mm x 2.5mm dimensions to prevent soldering defects during reflow.

Oscillators Selection Notes

Select this model when a balance between tight frequency stability and low cost is required. The MEMS construction offers superior vibration tolerance over quartz alternatives. Consider the 3.3V operating voltage to ensure compatibility with standard logic levels in modern digital circuits without additional level shifting.

Oscillators Part Context

This part belongs to the EMK43 series of MEMS oscillators from Ecliptek. The series provides various frequency options within a standardized small outline package. The H2J designation indicates specific pinout and electrical characteristics consistent with the LVCMOS family, ensuring interchangeability within the same product line for different frequency needs.

Oscillators Replacement Considerations

Direct replacements include other EMK43 series variants with matching 50MHz frequencies and ±25 ppm stability. Verify that substitute components maintain the same 3.3V supply requirement and LVCMOS output swing to avoid signal integrity issues in existing designs.
