TWEAACJANF-12.800000

Oscillators Overview

The TWEAACJANF-12.800000 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by Taitien. It operates at a nominal frequency of 12.8 MHz with CMOS output levels. The device supports a supply voltage range of 2.8 V to 3.3 V and features a control voltage input for frequency adjustment. It offers a pulling capability of ±5.0 ppm and frequency stability of ±0.5 ppm. The operating temperature range is specified from -20°C to +70°C. The component is housed in a compact 4-SMD, No Lead surface mount package.

Oscillators Feature Summary

• Integrates temperature compensation circuitry to maintain frequency stability across varying thermal conditions.
• Provides adjustable frequency output via an external control voltage interface.
• Delivers standard CMOS logic level signals suitable for digital clock distribution.
• Utilizes a leadless surface mount package design for automated assembly integration.

Oscillators Applications

• Precision timing reference sources in communication equipment
• Clock generation modules for embedded systems requiring stable frequencies
• Frequency synthesis circuits utilizing voltage-controlled tuning
• Consumer electronics requiring compact high-stability oscillators

Oscillators Procurement Notes

Verify the specific revision status and pinout configuration against the official manufacturer datasheet prior to implementation. Ensure that the control voltage supply matches the required pulling specifications. Confirm that the PCB layout accommodates the 4-SMD no-lead package dimensions and thermal requirements. Cross-reference the part number suffixes to ensure compatibility with the intended supply voltage and output drive strength.

Oscillators Selection Notes

Select this component when a balance between size, cost, and moderate frequency stability is required. It is appropriate for applications where ±0.5 ppm stability is sufficient and active temperature compensation is needed without the complexity of a full TCXO. Consider the ±5.0 ppm pulling range if frequency fine-tuning is necessary during system calibration. Evaluate the CMOS output drive capability against the load requirements of the destination circuit.

Oscillators Part Context

This oscillator belongs to Taitien's VCTCXO product line, designed for applications needing better stability than standard VCXOs but with lower power consumption and cost than full TCXOs. The 12.8 MHz frequency is commonly used in telecommunications and data conversion interfaces. The series utilizes quartz crystal resonators integrated with compensation networks to minimize frequency drift due to ambient temperature changes.

Oscillators Replacement Considerations

Direct substitutes include other Taitien VCTCXOs with identical 12.8 MHz frequency, 4-SMD package, and CMOS output, such as the TWEAACSANF-12.800000. Verify that alternative parts match the 2.8-3.3V supply range and ±0.5 ppm stability specification. Ensure the replacement maintains the same control voltage sensitivity and pulling range to preserve system performance.
