7L-40.000MDN-T

Oscillators Overview

The TXC CORPORATION 7L-40.000MDN-T is a temperature-compensated crystal oscillator (TCXO) operating at a fundamental frequency of 40 MHz. It utilizes a clipped sine wave output signal and functions with a supply voltage of 1.8V. The component features a surface-mount package measuring 2.5 mm in length, 2.0 mm in width, and 0.8 mm in height, utilizing a four-terminal no-lead configuration. Key electrical specifications include a maximum supply current of 2 mA and an equivalent series resistance of 80 ohms. The device supports a load capacitance of 12 pF and maintains a frequency stability tolerance of ±30 ppm across the operational range.

Oscillators Feature Summary

• Integrated temperature compensation for enhanced frequency stability
• Low-power operation suitable for portable electronics
• Compact surface-mount footprint for space-constrained designs

Oscillators Applications

Oscillators Procurement Notes

Verify the specific supply voltage requirement of 1.8V against your system design to ensure compatibility. Confirm that the clipped sine wave output matches the input requirements of your downstream circuitry. Check the physical dimensions of the 2.5 x 2.0 x 0.8 mm package against your PCB layout constraints. Ensure the thermal environment remains within the specified operating temperature range to maintain the stated frequency stability.

Oscillators Selection Notes

Select this component when a low-profile TCXO is required for 40 MHz applications. Consider the 1.8V supply constraint if designing for battery-operated systems. Compare the clipped sine wave output against other waveform options if your application requires a square wave or CMOS output. Evaluate the ±30 ppm stability against tighter precision requirements that might necessitate a higher-grade variant.
