TTEATLJANF-40.000000

Oscillators Overview

The TTEATLJANF-40.000000 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by Taitien, operating at a nominal frequency of 40 MHz. It features a clipped sine wave output and is supplied in a compact 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm x 1.00mm. The device operates on a single supply voltage of 3.3V with a maximum current consumption of 6mA. It provides a frequency stability of ±4.6ppm across an industrial temperature range of -40°C to +85°C. The component supports electronic frequency control via a control voltage input, enabling precise tuning for applications requiring stable clock signals.

Oscillators Feature Summary

• Industrial equipment utilizing synchronized data transmission

Oscillators Procurement Notes

Verify the specific revision level and pin configuration against the official manufacturer datasheet before integration. Confirm that the 3.3V supply requirement aligns with the target system's power rails. Ensure thermal management strategies account for the specified operating temperature range to maintain the stated frequency stability metrics during prolonged operation.

Oscillators Selection Notes

Select this component when high frequency stability within a small form factor is required. The VCTCXO architecture offers better performance than standard TCXOs while maintaining lower power consumption than higher-end OCXO solutions. Consider the control voltage interface requirements and ensure the application can accommodate the necessary tuning circuitry for optimal performance.

Oscillators Part Context

This oscillator belongs to Taitien's series of precision timing devices, specifically designed for applications demanding reliable clock sources in portable and industrial electronics. The 40 MHz frequency is commonly used as a reference clock for microcontrollers and communication interfaces. The no-lead package design facilitates improved thermal dissipation and solder joint reliability compared to traditional leaded packages.

Oscillators Replacement Considerations

Direct substitutes must match the 40 MHz frequency, VCTCXO type, 3.3V supply, and 4-SMD footprint. Verify equivalent frequency stability and control voltage specifications from alternative manufacturers to ensure functional compatibility without redesigning the host circuit board.
