7Z-38.400MCG-T

Oscillators Overview

The 7Z-38.400MCG-T is a temperature-compensated crystal oscillator (TCXO) manufactured by TXC Corporation, designed for precision timing applications requiring high frequency stability across varying thermal conditions. Operating at a nominal frequency of 38.4 MHz, this component utilizes a quartz or ceramic resonator element housed in a compact 2.5 mm x 2.0 mm surface-mount package with four pins and no lead configuration. It supports a supply voltage range typically centered around 2.5V to 3.3V, delivering a clipped sine wave output format suitable for low-noise digital interfaces. The device achieves a frequency stability of ±0.5 ppm over an extended industrial temperature range of -30°C to +85°C, ensuring reliable performance in demanding environments where standard oscillators might drift significantly due to thermal fluctuations.

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage levels and output formats. Confirm that the selected variant matches the intended operating temperature range and stability specifications for your application. Check for any recent product change notifications or lifecycle status updates from TXC Corporation before finalizing procurement plans.

Oscillators Selection Notes

Choose this component when high frequency stability is critical and space limitations preclude larger oscillator packages. Ensure the system power supply aligns with the specified voltage requirements to maintain optimal performance. Consider the output load capacitance and drive level requirements of the connected circuitry to prevent frequency pulling or damage to the oscillator element during operation.

Oscillators Part Context

This TCXO belongs to the 7Z series of controlled oscillators from TXC Corporation, which focuses on providing miniaturized solutions for modern electronics. The series is characterized by its ability to deliver superior stability compared to standard crystal oscillators while maintaining a small physical profile. These components are integral to timing subsystems where accuracy and reliability under thermal stress are paramount.

Oscillators Replacement Considerations

Direct substitutes may include other 38.4 MHz TCXOs from TXC with similar pinouts and stability ratings, such as variants within the same 7Z family. Cross-referencing with competitors like Abracon or SiTime requires careful verification of electrical parameters and mechanical dimensions to ensure board-level compatibility.
