EC2645ETTTS-14.31818M TR

Oscillators Overview

The EC2645ETTTS-14.31818M TR is a standard clock oscillator manufactured by Ecliptek, operating at a nominal frequency of 14.31818 MHz. It utilizes an LVCMOS output format and requires a supply voltage of 3.3 Vdc with a tolerance of ±10%. The device features a maximum current consumption of 18 mA and provides tri-state control via Pin 1 for enable/disable functionality. Frequency stability is rated at ±50 ppm across the full operating temperature range of -40°C to +85°C. The component is housed in a 4-pad ceramic surface-mount package measuring 5.0 mm x 7.0 mm.

Oscillators Feature Summary

• Integrated tri-state control on Pin 1 allows for high-impedance output disabling to reduce power consumption during standby modes.
• Constructed with a ceramic surface-mount package designed for robust performance in industrial-grade environments.
• Delivers stable LVCMOS clock signals with specified jitter characteristics suitable for high-speed digital interfaces.

Oscillators Applications

• Industrial gateway reference clock solutions
• High-speed data communication equipment
• PCIe and Gigabit Ethernet interface timing
• Battery-powered devices requiring low-power standby states

Oscillators Procurement Notes

Verify that the specific part number matches the required 3.3V supply voltage and 14.31818 MHz frequency before procurement. Confirm that the application circuit supports the 15 pF maximum output load specification to maintain duty cycle integrity. Ensure the PCB layout accommodates the 5.0 mm x 7.0 mm footprint and adheres to the recommended reflow soldering profiles to prevent thermal damage to the ceramic package.

Oscillators Selection Notes

Select this component when a 3.3V logic level and industrial temperature range are mandatory. The integrated tri-state feature makes it suitable for systems requiring dynamic clock gating without external switching components. Consider the 50 ppm stability requirement against system timing budgets. This model is appropriate for designs prioritizing low standby current through hardware-controlled output disable capabilities.

Oscillators Part Context

This oscillator belongs to the EC2645ETTTS series, which represents Ecliptek's line of industrial-grade quartz crystal oscillators. The series is characterized by its ceramic packaging and support for various frequencies within the standard clock spectrum. The 'TTS' suffix indicates the inclusion of tri-state functionality, distinguishing it from non-tri-state variants in the same physical footprint family.

Oscillators Replacement Considerations

Direct substitutes must match the 3.3V supply, 14.31818 MHz frequency, and 5x7mm ceramic package. Verify that any replacement also includes Pin 1 tri-state control if power management is required. Cross-reference stability ratings and output load specifications to ensure compatibility with existing drive circuits.

Oscillators FAQ

How is the tri-state function activated?

The output is disabled (high impedance) when Pin 1 is pulled to a voltage less than or equal to 0.3Vdd. The output is enabled when Pin 1 is connected to no connect or pulled to a voltage greater than or equal to 0.7Vdd.

What is the maximum output load capacitance?

The maximum output load capacitance is 15 pF. Exceeding this limit may degrade the duty cycle and rise/fall times.
