EC5625ETTTS-4.000M TR

Oscillators Overview

The EC5625ETTTS-4.000M TR is a standard quartz crystal oscillator (SPXO) from the Ecliptek EC56 series, housed in a compact 2.0mm x 2.5mm ceramic surface-mount package with four pads. It operates at a nominal frequency of 4.000MHz and requires a 3.3Vdc supply voltage. The device features LVCMOS output logic and provides a frequency stability of ±25ppm across an industrial operating temperature range of -40°C to +85°C. Key electrical characteristics include a maximum input current of 7mA, a load drive capability of 15pF, and a maximum RMS phase jitter of 1ps within the 12kHz to 20MHz offset range. The unit supports a three-state control function for power management.

Oscillators Feature Summary

• Integrated three-state enable/disable pin allows for low-power standby operation via high-impedance output
• Compliant with EU RoHS and REACH regulations for lead-free manufacturing and environmental safety

Oscillators Applications

• Low-speed microcontroller system clock generation
• Reference clock source for ADC sampling circuits
• Clock signal provision for IoT gateway modules
• Timing reference for general-purpose digital logic interfaces

Oscillators Procurement Notes

Verify that the specific order suffix matches the required packaging format, as the part number indicates tape-and-reel delivery. Confirm that the ±25ppm stability rating aligns with the target application's timing requirements, noting that this value represents the total allowable deviation across the specified industrial temperature range and supply voltage conditions. Ensure the 3.3V supply rail remains stable within the operational limits to maintain frequency accuracy.

Oscillators Selection Notes

Select this component when a small form factor is critical but industrial temperature performance is required. The 4MHz frequency suits applications where lower clock speeds reduce electromagnetic interference compared to higher-frequency alternatives. Consider the 15pF load drive capability to ensure compatibility with downstream inputs without additional buffering. The three-state feature offers flexibility for power-sensitive designs requiring clock gating capabilities during idle periods.

Oscillators Part Context

This model belongs to the Ecliptek EC56 series, which focuses on providing balanced performance in ultra-small packages. The series targets modern electronics where board real estate is limited, offering a significant size reduction compared to traditional 3225 or larger oscillator footprints. It serves as a direct replacement for legacy components in compact consumer and industrial devices, bridging the gap between miniaturization and reliable timing precision.

Oscillators FAQ

How does the three-state control function operate?

The three-state control is managed via Pin 1. Connecting this pin to a voltage above 90% of Vdd or leaving it floating enables the clock output. Pulling Pin 1 below 10% of Vdd forces the output into a high-impedance state, effectively disabling the clock.

What constitutes the ±25ppm frequency stability specification?

The ±25ppm figure represents the total frequency deviation over the entire operating life and conditions. It includes initial calibration error, temperature drift across the -40°C to +85°C range, voltage fluctuations, load changes, aging effects, and mechanical shock or vibration impacts.
