8P-38.400MDS-T

Oscillators Overview

The 8P-38.400MDS-T is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by TXC Corporation. It operates at a nominal frequency of 38.4 MHz with a frequency stability of ±2.0 ppm over the temperature range of -30°C to +85°C. The device utilizes a quartz resonator housed in a compact 2.0 mm x 1.6 mm surface-mount package and requires a supply voltage of 1.8 V. It features an AFC center control voltage of 0.9 V and outputs a clipped sine wave signal, designed for applications requiring precise frequency control within a small form factor.

Oscillators Feature Summary

• Integrates voltage-controlled temperature compensation for high frequency stability across defined operating temperatures.
• Utilizes a miniature 2.0x1.6 mm surface-mount package suitable for space-constrained designs.
• Outputs a clipped sine wave signal optimized for low electromagnetic interference.

Oscillators Applications

• Mobile communication devices requiring stable clock sources
• Wireless networking equipment
• Portable electronic systems with strict size limitations

Oscillators Procurement Notes

Verify that the specific application environment falls within the -30°C to +85°C operational range to ensure the ±2.0 ppm stability specification is met. Confirm that the system power supply provides a clean 1.8 V rail, as voltage fluctuations may impact frequency accuracy. Ensure the design accommodates the 0.9 V AFC center voltage requirement for proper tuning range alignment. Cross-reference the latest datasheet for pin configuration and thermal management guidelines before finalizing the layout.

Oscillators Selection Notes

Select this component when a balance between high precision and minimal physical footprint is required. The 1.8 V operation makes it suitable for modern low-power digital circuits. Consider the clipped sine wave output format against load requirements; if square waves are needed, additional buffering or different oscillator types should be evaluated. The ±2.0 ppm stability is superior to standard TCXOs but may differ from higher-grade alternatives.

Oscillators Part Context

This part belongs to the 8P series of voltage-controlled oscillators from TXC Corporation. It is distinct from standard TCXOs due to its voltage control input, allowing for fine-tuning of the output frequency. The series is characterized by its use of quartz technology combined with ceramic packaging elements to achieve reliability in harsh environments while maintaining a small profile compared to larger through-hole or standard SMD oscillators.

Oscillators Replacement Considerations

The 525M38420DTR from CTS Corporation is documented as a comparable alternative. Verify that the replacement matches the 1.8 V supply, 38.4 MHz frequency, and ±2.0 ppm stability specifications. Check for compatibility regarding the AFC control voltage range and output waveform type before substitution.
