8P-38.400MBS-T

Oscillators Overview

The 8P-38.400MBS-T is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by TXC Corporation. It operates at a nominal frequency of 38.4 MHz and utilizes a quartz resonator element. The device is designed for surface-mount assembly in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. It functions on a single 3.3V supply voltage and outputs a clipped sine wave signal. Key electrical characteristics include a control sensitivity of 50mV/ppt and a pullability range of +/- 75ppm. Frequency stability is specified at +/- 0.5ppm over the industrial temperature range of -30°C to +85°C.

Oscillators Feature Summary

• Integrates voltage-controlled tuning for precise frequency adjustment via external control voltage.
• Provides high frequency stability through internal temperature compensation circuitry.
• Features a low-profile surface-mount footprint suitable for space-constrained PCB layouts.
• Outputs a clipped sine wave signal compatible with standard digital input interfaces.

Oscillators Applications

• Wireless communication modules requiring stable clock references
• Portable electronic devices with limited power budgets
• Industrial control systems operating in variable thermal environments

Oscillators Procurement Notes

Verify that the specific order suffix matches the required voltage and output waveform specifications. Confirm that the design accommodates the 4-SMD no-lead package dimensions and soldering profile. Ensure the application circuit provides the necessary control voltage range to achieve the specified pullability without exceeding maximum ratings. Check for RoHS compliance documentation if environmental regulations apply to the final product.

Oscillators Selection Notes

Select this component when a small form factor VCTCXO is required for 38.4 MHz applications. Consider the 3.3V supply constraint and clipped sine wave output compatibility with downstream logic. Evaluate the need for voltage control against fixed-frequency alternatives like the 7Z series if tuning is not required. Assess the thermal environment to ensure the -30°C to +85°C range meets operational requirements.

Oscillators Part Context

This oscillator belongs to the TXC 8P Series, which focuses on compact VCTCXO solutions. The series is characterized by its small 2.0x1.6mm package size and integration of quartz crystal technology within a surface-mount format. It serves as a specialized timing solution distinct from standard XO or TCXO models that lack voltage control capabilities.

Oscillators Replacement Considerations

The 8P-38.400MCG-T is a similar part within the same series but operates at 2.5V with Enable/Disable functionality instead of amplitude control. Verify voltage compatibility and pinout differences before substitution.
