EC3645TTS-100.000M TR

Oscillators Overview

The EC3645TTS-100.000M TR is a standard quartz crystal oscillator manufactured by Ecliptek, operating at a nominal frequency of 100 MHz. It utilizes an LVCMOS output format and requires a 3.3 Vdc supply voltage with a tolerance of ±10%. The device features a frequency stability of 50 ppm across its operating temperature range of -10°C to +70°C. Packaged in a compact 4-SMD surface-mount configuration measuring 5.0 mm by 3.2 mm, it supports a maximum load capacitance of 15 pF. The component includes a tri-state enable pin for power management and complies with RoHS standards.

Oscillators Feature Summary

• Features a dedicated tri-state control pin that allows the output to be disabled for low-power standby modes.
• Provides stable clock signals with integrated compensation for temperature drift, voltage fluctuations, and aging effects.
• Designed for direct integration into high-speed digital circuits without requiring external buffering components.

Oscillators Applications

• Reference clock source for Gigabit Ethernet PHY transceivers
• System clock generation for industrial microcontrollers and gateways
• Timing reference for PCIe Gen1 peripheral interfaces

Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when placing orders. Confirm the operating temperature grade (-10C to +70C) matches the target application environment, as industrial variants may require different part numbers. Ensure the PCB footprint aligns with the 5.0mm x 3.2mm SMD dimensions. Cross-reference the manufacturer number with current distributor catalogs to confirm availability status.

Oscillators Selection Notes

Select this component when a 100 MHz LVCMOS signal is required within a 3.3V logic domain. It is suitable for applications where moderate frequency stability (50 ppm) is sufficient. Consider the 35mA maximum current consumption for power budgeting. Ensure the design accommodates the 15pF load capacitance limit on the output trace to maintain signal integrity.

Oscillators Part Context

This oscillator belongs to the EC36 series, which offers various frequencies and stability grades in a standardized 5032 package. The series is designed for general-purpose timing needs in consumer and industrial electronics. The EC3645TTS variant specifically targets the 100 MHz segment with standard commercial temperature ratings, providing a balance between performance and cost.

Oscillators Replacement Considerations

Direct substitutes include other 100MHz LVCMOS oscillators in 5032 packages from manufacturers such as Abracon or Epson. Verify equivalent parameters including supply voltage, output drive strength, and phase jitter specifications before substitution.
