VTEUPCJANF-19.440000

Oscillators Overview

The VTEUPCJANF-19.440000 is a Voltage-Controlled Crystal Oscillator (VCXO) manufactured by Taitien, operating at a nominal frequency of 19.44 MHz. It utilizes a crystal base resonator and features CMOS output signals suitable for digital logic interfaces. The device supports an Enable/Disable function for power management control. It operates within a supply voltage range of 3.3V and functions reliably across a commercial temperature range of -20°C to +70°C. The component is housed in a compact 6-SMD, No Lead surface-mount package, designed for automated assembly processes.

Oscillators Feature Summary

• Voltage-controlled operation with CMOS output interface
• Integrated enable/disable functionality for power management
• Compact 6-SMD surface-mount packaging

Oscillators Applications

• Telecommunications systems requiring precise frequency control
• Data acquisition equipment needing stable clock sources
• Synchronization applications demanding low jitter performance

Oscillators Procurement Notes

Verify the current product status before procurement, as this specific part number may be listed as obsolete or no longer manufactured in certain distributor catalogs. Confirm availability through authorized Taitien channels or verified distributors. Ensure that the 3.3V supply requirement and -20°C to +70°C operating temperature range align with your system design constraints. Cross-reference the 6-SMD package dimensions against your PCB footprint specifications to guarantee mechanical compatibility during integration.

Oscillators Selection Notes

Select this VCXO when a voltage-tunable frequency source is required for synchronization tasks. The CMOS output simplifies interfacing with standard digital circuits without additional buffering. Consider the commercial temperature range (-20°C to +70°C) against your environmental conditions. If industrial-grade stability or extended temperature ranges are needed, evaluate alternative Taitien series such as TCETTCJANF or TSETTCJANF which offer wider operational limits and higher precision specifications.

Oscillators Part Context

This component belongs to Taitien's oscillator family, specifically designed for applications requiring frequency agility. Unlike fixed-frequency oscillators, VCXOs allow minor frequency adjustments via a control voltage, making them ideal for phase-locked loops. The 19.44 MHz frequency is commonly used in telecommunications standards. The transition from older manufacturing batches to current stock should be verified, as some listings indicate this model may be discontinued in favor of newer variants with improved stability or different package options.

Oscillators Replacement Considerations

For direct replacements, consider the VWEUPCJANF-19.440000 if available, which shares similar VCXO characteristics. Verify pinout compatibility and electrical parameters before substitution.
