TSEATLSANF-20.000000

Oscillators Overview

The TSEATLSANF-20.000000 is a temperature-compensated crystal oscillator (TCXO) manufactured by Taitien, designed for surface-mount applications. It operates at a fundamental frequency of 20 MHz with a clipped sine wave output signal. The device supports a supply voltage range of 3.3V and features an enable/disable control function for power management. It utilizes a 10-SMD, no-lead package configuration, measuring approximately 3.2mm in length and 2.5mm in width, with a maximum height of 1.0mm. The unit offers high frequency stability of ±0.28ppm across an operating temperature range of -40°C to +85°C, ensuring reliable performance in demanding electronic environments.

Oscillators Feature Summary

• Integrated temperature compensation circuitry ensures stable frequency output across wide thermal variations

• Compact 10-SMD no-lead surface mount package design facilitates automated PCB assembly
• Delivers clipped sine wave output suitable for digital clock distribution applications

Oscillators Applications

• Wireless communication base stations requiring precise timing references
• Portable electronic devices needing low-power oscillators with enable capabilities
• Industrial control systems operating in extreme temperature environments
• Network infrastructure equipment demanding high frequency stability

Oscillators Procurement Notes

Verify the specific package type against your PCB footprint requirements, as this model uses a 10-SMD no-lead configuration distinct from standard 4-pin variants. Confirm that the 3.3V supply voltage aligns with your system's power rails before integration. Ensure the enable/disable control logic matches your microcontroller or FPGA GPIO capabilities. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate the ±0.28ppm stability specification against your application's jitter tolerance requirements.

Oscillators Selection Notes

Choose this component when high stability and thermal compensation are critical for system timing accuracy. The 10-SMD package offers a larger footprint than 4-pin alternatives, which may impact board space constraints. Consider the enable feature if power conservation during idle states is a priority. Compare the ±0.28ppm stability against less expensive TCXOs if cost is a primary driver. Ensure the clipped sine wave output is compatible with your input receiver thresholds.

Oscillators Part Context

This oscillator belongs to Taitien's broader family of temperature-compensated crystal oscillators, distinguished by its specific 10-SMD package and enable functionality. Unlike basic VCTCXO models such as the TXEACDSANF series, this part provides enhanced thermal stability through active compensation rather than voltage control. The 20MHz frequency places it within common clocking standards for digital interfaces. Its design prioritizes reliability in harsh environments over minimal size, differentiating it from smaller 4-pin SMD oscillators.

Oscillators Replacement Considerations

Direct substitutes include other Taitien TCXOs with similar stability and package dimensions, such as TWETALSANF-20.000000, though pinout compatibility must be verified. Cross-brand replacements require matching the 10-SMD no-lead form factor and 3.3V operation. Ensure any alternative maintains the ±0.28ppm stability and -40°C to +85°C temperature range. Verify that the enable/disable control mechanism is supported by the replacement part to maintain system power management functionality.
