TFETALSANF-40.000000

Oscillators Overview

The TFETALSANF-40.000000 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by Taitien, operating at a nominal frequency of 40 MHz. It utilizes a clipped sine wave output and requires a supply voltage of 2.8V. The device features high frequency stability of ±500 ppb and operates within an extended temperature range of -40°C to 85°C. Maximum supply current is 4 mA. The component is housed in a 14-DIP package with four leads, specifically designed as a full-size metal can for robust surface or through-hole integration.

Oscillators Feature Summary

• High frequency stability of ±500 ppb ensures precise timing performance.
• Extended industrial temperature operation from -40°C to 85°C.
• Clipped sine wave output suitable for digital clocking applications.
• Robust full-size metal can packaging provides environmental protection.

Oscillators Applications

• Industrial communication systems requiring stable clock sources
• Test and measurement equipment needing low phase noise
• Telecommunications base station modules
• Automotive electronics operating in harsh thermal environments

Oscillators Procurement Notes

Verify the specific pinout configuration against the official datasheet before PCB layout finalization, as DIP packages may vary in lead spacing. Confirm that the 2.8V supply rail meets the maximum current requirements of 4 mA under all load conditions. Ensure the design accommodates the physical dimensions of the full-size metal can package to prevent mechanical interference during assembly.

Oscillators Selection Notes

Select this component when superior frequency stability compared to standard TCXOs is required, indicated by the ±500 ppb specification. The wide operating temperature range makes it suitable for applications exceeding standard commercial limits. Consider the metal can package for enhanced shielding needs. Compare power consumption and form factor against smaller SMD alternatives if space constraints exist.

Oscillators Part Context

This part belongs to Taitien's oscillator family, specifically designed for applications demanding high precision. It complements other series like TXKADCSANF and TYETCCSANF but distinguishes itself through its DIP metal can format and exceptional stability metrics. It serves as a specialized solution for industrial and telecom sectors where reliability and accuracy are critical parameters.

Oscillators Replacement Considerations

No direct substitute part numbers are confirmed in public documentation. Evaluate alternative Taitien models such as TYETBLSANF-40.000000 only if package compatibility and electrical specifications align perfectly. Verify that any replacement maintains the same frequency stability and temperature range requirements.
