7L-38.400MDS-T

Oscillators Overview

The 7L-38.400MDS-T is a temperature-compensated crystal oscillator (TCXO) manufactured by TXC Corporation, operating at a nominal frequency of 38.4 MHz. It utilizes a clipped sine wave output format and requires a supply voltage of 2.5V. The device features high frequency stability with a typical accuracy of ±1.5 ppm over the industrial temperature range of -40°C to +85°C. Packaged in a compact 4-SMD, no-lead surface-mount footprint measuring 2.5mm x 2.0mm x 0.8mm, it is designed for applications requiring precise timing signals.

Oscillators Feature Summary

• Temperature compensation ensures stable frequency performance across wide thermal variations
• Compact surface-mount package facilitates automated assembly and space-constrained designs
• Clipped sine wave output provides clean signal integrity for sensitive receiver circuits

Oscillators Applications

• Satellite navigation systems requiring high precision timing
• Wireless communication base stations and modules
• Network synchronization equipment

Oscillators Procurement Notes

Verify the specific suffix 'D' against official datasheets to confirm the exact frequency tolerance grade, as suffixes define stability parameters. Ensure the 2.5V supply requirement matches the target system's power rails. Confirm RoHS compliance status through the manufacturer's latest documentation before integration.

Oscillators Selection Notes

Select this component when superior frequency stability compared to standard XO types is required without the complexity of OCXOs. The 2.5V supply voltage suits low-power portable devices. Consider the clipped sine wave output compatibility with downstream logic or RF front-ends that accept analog-style clock inputs rather than digital CMOS levels.

Oscillators Part Context

This part belongs to the 7L series of TCXOs from TXC Corporation, which are engineered for high-stability applications. The series is commonly used in satellite positioning and telecommunications where environmental temperature fluctuations would otherwise degrade timing accuracy in standard oscillators.

Oscillators Replacement Considerations

The 7L-38.400MCN-T is listed as a parameter-equivalent alternative within the same product family. Verify that the specific stability and pinout configurations match the design requirements before substitution.
