TTEAALJANF-20.000000

Oscillators Overview

The TTEAALJANF-20.000000 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by Taitien. It operates at a nominal frequency of 20 MHz with a CMOS output signal. The device is designed for surface mount installation in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a maximum seated height of 0.083 inches. It functions on a 3.3V supply voltage and draws a maximum current of 6mA. The unit supports enable/disable functionality and operates within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Voltage-controlled temperature compensation for enhanced frequency stability across varying thermal conditions
• CMOS logic output compatible with standard digital interfaces
• Integrated enable and disable control pin for power management

Oscillators Applications

• Mobile communication devices requiring stable clock signals
• Wireless networking equipment
• Portable electronic systems with strict power constraints

Oscillators Procurement Notes

Verify the specific frequency tolerance and pull range requirements against your system design before procurement. Confirm that the exposed pad thermal termination matches your PCB footprint guidelines. Ensure the 3.3V supply rail meets the current sourcing capabilities required for the 6mA maximum load. Cross-reference the package dimensions with your assembly equipment specifications to ensure compatibility.

Oscillators Selection Notes

Select this component when voltage-controlled tuning is necessary to compensate for environmental temperature fluctuations. The VCTCXO architecture offers superior stability compared to standard XO types while maintaining lower power consumption than higher-end OCXO solutions. Consider the 4-pin SMD form factor for space-constrained layouts where thermal performance is critical.

Oscillators Part Context

This oscillator belongs to Taitien's TT series of precision timing components. It complements other models like the OXETDLJANF-20.000000 standard XO and the TWETMLSAYF-20.000000 TCXO by providing active voltage control for frequency adjustment. The series emphasizes compact surface-mount packaging suitable for modern high-density electronics manufacturing processes.

Oscillators Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate alternative VCTCXOs from Taitien or other manufacturers that match the 20 MHz frequency, 3.3V supply, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics before substitution.
