EC5645ETTTS-48.000M TR

Oscillators Overview

The EC5645ETTTS-48.000M TR is a CMOS Quartz Crystal Clock Oscillator (XO) manufactured by Ecliptek, operating at a nominal frequency of 48.000MHz. It utilizes an LVCMOS output logic format powered by a 3.3Vdc supply with a maximum input current of 12mA. The device features a 4-pad ceramic surface mount package measuring 2.0mm x 2.5mm. Frequency stability is specified at ±50ppm across the full operating temperature range of -40°C to +85°C, inclusive of calibration tolerance, aging, and environmental factors. Maximum aging is 5ppm/year, with a duty cycle of 50±10% and rise/fall times under 6ns.

Oscillators Feature Summary

• Integrated quartz crystal oscillator providing stable clock signals for digital circuits
• LVCMOS output interface compatible with standard 3.3V logic systems
• Compact ceramic surface mount construction suitable for space-constrained designs
• Tri-state control capability on Pin 1 for power management

Oscillators Applications

• Industrial gateway reference clocks
• Low-power IoT device timing sources

Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm RoHS compliance status matches project requirements, as documentation indicates lead-free composition. Ensure the supplier provides the official datasheet revision G or later to validate electrical parameters. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during procurement.

Oscillators Selection Notes

Select this component for applications requiring a 48MHz clock source in a minimal footprint. The ±50ppm stability covers total error including temperature drift and aging, simplifying design calculations. The 3.3V supply voltage aligns with common industrial standards. Consider the tri-state pin functionality if power-down modes are required in the system architecture.

Oscillators Part Context

This oscillator belongs to the EC56 series, designed for general-purpose timing needs. It replaces larger through-hole crystals or older SMD packages. The 2025 ceramic package offers improved thermal and mechanical reliability compared to plastic variants. It serves as a direct replacement for similar 48MHz oscillators in existing PCB layouts without modification.

Oscillators Replacement Considerations

Compatible substitutes include other 48MHz SPXOs in 2025 packages with matching 3.3V LVCMOS outputs. Verify that alternative parts meet the same ±50ppm total stability and -40°C to +85°C temperature range specifications to ensure functional equivalence.
