EC2645ETTS-50.000M TR

Oscillators Overview

The Ecliptek EC2645ETTS-50.000M TR is a 50 MHz standard crystal oscillator housed in a 4-pin, 5mm x 7mm ceramic surface-mount package. It operates on a 3.3V supply with ±10% tolerance and delivers an LVCMOS output signal. The device ensures a total frequency stability of ±50 ppm across the industrial temperature range of -40°C to +85°C, accounting for calibration, thermal drift, voltage variations, load changes, aging, and mechanical shock. It features a tri-state control pin for enable/disable functionality, allowing standby current reduction to 10 μA. The component supports a maximum load of 15 pF and exhibits RMS phase jitter of 1 ps within the 12 kHz to 20 MHz offset range.

Oscillators Feature Summary

• Industrial-grade frequency stability of ±50 ppm over the full operating temperature range
• Tri-state control pin enables low-power standby mode with minimal current consumption
• Low phase jitter suitable for high-speed digital interfaces and communication systems
• RoHS compliant lead-free construction for environmental safety

Oscillators Applications

• Reference clock source for industrial gateways and routers
• Clock generation for Gigabit Ethernet MAC interfaces
• Timing reference for PCIe 2.0 and similar high-speed bus architectures
• Battery-powered industrial equipment requiring low standby power

Oscillators Procurement Notes

Verify that the specific part number matches the required ±50 ppm stability specification, as other variants in the series may offer different tolerances. Confirm the package dimensions are compatible with the PCB footprint, noting the 5mm x 7mm ceramic SMD form factor. Ensure the design accounts for the 15 pF maximum load capacitance to maintain signal integrity. Check that the manufacturing process adheres to the specified reflow soldering profiles to prevent thermal damage during assembly.

Oscillators Selection Notes

Select this component when a stable 50 MHz reference is needed for industrial applications requiring wide temperature operation. It is appropriate for designs prioritizing low standby power through the tri-state feature. Consider this part for systems where phase jitter must be minimized for reliable data transmission. Evaluate the trade-off between the ±50 ppm stability and cost against consumer-grade alternatives if extreme precision is not critical.

Oscillators Part Context

This oscillator belongs to the EC26 series from Ecliptek, designed for robust performance in demanding environments. The series typically includes various frequency options and stability grades. The EC2645 variant specifically targets industrial markets with its extended temperature range and comprehensive stability metrics. It serves as a direct replacement for legacy oscillators requiring similar form factors and electrical characteristics.

Oscillators Replacement Considerations

Direct substitutes include other 50 MHz LVCMOS oscillators in 5x7mm packages with comparable ±50 ppm stability. Verify compatibility regarding supply voltage, output drive strength, and pinout configuration. Ensure any replacement maintains the same RoHS compliance and industrial temperature rating.
