EC3645TS-50.000M TR

Oscillators Overview

The EC3645TS-50.000M TR is a CMOS quartz crystal clock oscillator (SPXO) manufactured by Ecliptek. It operates at a nominal frequency of 50 MHz with an LVCMOS output interface. The device requires a 3.3 Vdc supply voltage and features a 4-pad surface mount ceramic package measuring 3.2 mm x 5.0 mm. Key electrical specifications include a maximum frequency stability of 50 ppm, a rise time of 4 ns, and a tri-state enable/disable function. The operational temperature range spans from -20 °C to +70 °C.

Oscillators Feature Summary

• Integrates a tri-state high impedance control pin for standby power-down functionality
• Utilizes a compact 4-pin ceramic surface mount package for space-constrained designs
• Provides stable LVCMOS output signals suitable for digital logic interfaces

Oscillators Applications

• Industrial gateway reference clocks
• High-speed communication equipment timing sources
• Battery-powered industrial devices requiring low-power standby modes

Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm that the requested part matches the 3.2mm x 5.0mm footprint rather than larger variants like the 5x7mm EC26 series. Ensure compatibility with RoHS and REACH compliance standards required for export markets. Cross-reference the manufacturer designation between Ecliptek and Abracon to ensure correct component identification during procurement.

Oscillators Selection Notes

Select this component when a 50 MHz LVCMOS clock source is required within a -20 °C to +70 °C operating window. The 50 ppm stability specification supports general-purpose digital synchronization tasks. Consider the integrated tri-state feature if system-level power management necessitates clock disable capabilities without external switching circuitry. Evaluate the 3.2mm x 5.0mm package dimensions against available PCB real estate constraints.

Oscillators Part Context

This oscillator belongs to the EC36 series of standard quartz crystal oscillators designed for commercial and industrial applications. The series emphasizes reliability through lead-free construction and compliance with environmental directives. The model represents a fixed-frequency solution intended to replace discrete crystal and oscillator circuits in modern electronic assemblies.

Oscillators Replacement Considerations

Direct substitutes may include other 50 MHz LVCMOS oscillators in similar SMD packages from manufacturers such as Abracon or Epson. Verify that replacement parts maintain identical pinout configurations and voltage levels to ensure board compatibility.
