EC3645ETTTS-12.000M TR

Oscillators Overview

The EC3645ETTTS-12.000M TR is a standard clock oscillator manufactured by Ecliptek, operating at a nominal frequency of 12.000 MHz. It utilizes an LVCMOS output format and requires a 3.3 Vdc supply voltage. The device features a frequency stability of ±50 ppm across its operational range. Designed for surface-mount technology, it is housed in a compact ceramic package measuring 5.0 mm in length and 3.2 mm in width. The component supports a tri-state enable/disable function and operates within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Provides stable LVCMOS clock signals with tri-state control capability
• Constructed in a compact 5.0mm x 3.2mm ceramic SMD package
• Compliant with RoHS standards and lead-free manufacturing processes

Oscillators Applications

• Industrial gateway hardware reference clocks
• Ethernet PHY interface timing sources
• General-purpose microcontroller system clocks

Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when placing orders. Confirm that the 50 ppm stability rating aligns with the target application's jitter requirements. Ensure the 3.3V supply voltage matches the host system's power rails. Check for any specific REACH compliance documentation if exporting to regulated regions. Validate the -40°C to +85°C industrial temperature range against environmental conditions.

Oscillators Selection Notes

Select this model when a 12 MHz reference is required for digital interfaces like Ethernet or USB. The 50 ppm tolerance suits general communication protocols but may be insufficient for high-precision metrology. Consider the 15 pF load capacitance limit during PCB layout to maintain signal integrity. The tri-state pin allows for power management in low-power designs without external switching components.

Oscillators Part Context

This component belongs to the EC36 series of standard oscillators from Ecliptek. The series offers various frequencies and stability grades in a standardized 5032 footprint. It serves as a direct replacement for legacy crystal units requiring active drive capabilities. The product line emphasizes compliance with international environmental directives for global deployment.

Oscillators Replacement Considerations

Compatible substitutes include the EC3645ETTTS-12.000M (bulk packaging) and other EC36 series variants with matching 12 MHz frequency and 3.3V operation. Verify pinout compatibility before swapping. Ensure the replacement maintains the same ±50 ppm stability and -40°C to +85°C temperature range.
