TTEAALSANF-50.000000

Oscillators Overview

The TTEAALSANF-50.000000 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by Taitien. It operates at a nominal frequency of 50 MHz with a high stability of ±500 ppb. The device outputs a clipped sine wave and requires a 3.3V supply voltage, drawing a maximum current of 3.5mA. It is housed in a compact 4-SMD, No Lead package with an exposed pad, measuring 2.55mm x 2.05mm in footprint and 2.10mm in maximum seated height. The component supports surface mount installation and functions within an operating temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Provides precise frequency generation through internal temperature compensation mechanisms
• Utilizes voltage control for frequency adjustment capabilities
• Designed for low-power operation with minimal current consumption
• Features a compact surface-mount package suitable for space-constrained designs

Oscillators Applications

• Wireless communication systems requiring stable clock sources
• Portable electronic devices needing low power consumption
• Industrial equipment operating in varying temperature environments
• Navigation and positioning modules demanding high frequency accuracy

Oscillators Procurement Notes

Verify the specific output waveform requirement, as this model provides a clipped sine wave rather than a square wave. Confirm that the system design accommodates the 3.3V supply voltage and the 3.5mA maximum current draw. Ensure the PCB layout supports the 4-SMD no-lead package with an exposed thermal pad for proper mounting and heat dissipation. Check compatibility with the ±500 ppb stability specification against system timing requirements.

Oscillators Selection Notes

Select this component when high frequency stability is critical for applications involving mobile or variable thermal conditions. The VCTCXO architecture offers better performance than standard TCXOs while consuming less power than OCXOs. Consider the clipped sine wave output if the downstream circuitry can process this signal type directly. The wide operating temperature range makes it suitable for automotive or outdoor industrial use cases where environmental extremes are present.

Oscillators Part Context

This oscillator belongs to Taitien's line of controlled crystal oscillators, designed to replace less stable resonators in precision timing applications. It addresses the need for improved frequency accuracy over temperature variations compared to basic crystals. The 50 MHz frequency is commonly used in data conversion and processing interfaces. The series integrates compensation circuits to maintain performance across the specified temperature range without external components.
