7L26002009

Oscillators Overview

The 7L26002009 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by TXC Corporation. It operates at a frequency of 26 MHz with a stability of ±2 ppm. The device utilizes a crystal resonator and outputs a clipped sine wave signal. It functions within a supply voltage range of 2.5 V to 2.8 V, consuming a maximum current of 2 mA. The component is housed in a compact SMD package measuring 2.5 mm x 2.0 mm x 0.8 mm (4-SMD, no lead). It supports an operating temperature range from -30°C to +85°C and complies with RoHS3 standards.

Oscillators Feature Summary

• Temperature compensation ensures high frequency stability across varying environmental conditions
• Compact surface-mount design suitable for space-constrained electronic assemblies
• Low power consumption capability for energy-efficient system integration

Oscillators Applications

• Wireless communication modules requiring precise timing references
• Portable consumer electronics demanding low power operation
• Automotive infotainment and control systems
• Industrial instrumentation and data acquisition devices

Oscillators Procurement Notes

Verify the specific output waveform requirement, as this model provides a clipped sine wave rather than CMOS or LVCMOS signals. Confirm that the target circuitry can properly interface with sine wave outputs without additional buffering or conversion stages. Ensure the operating environment remains within the specified -30°C to +85°C thermal range to maintain the stated ±2 ppm stability performance.

Oscillators Selection Notes

Select this component when high frequency stability is critical but full oven-controlled oscillator (OCXO) performance is unnecessary. It serves as a suitable alternative to standard crystals where temperature-induced drift must be minimized. Consider the clipped sine wave output format during schematic design to ensure compatibility with downstream logic or RF stages. Evaluate the 2.5V to 2.8V supply voltage constraints against the system's power budget.

Oscillators Part Context

This part belongs to the 7L series of TCXOs from TXC Corporation, designed for applications requiring superior frequency accuracy compared to standard oscillators. The series targets markets sensitive to timing jitter and drift, such as telecommunications and precision measurement equipment. The 7L26002009 specifically addresses the need for stable 26 MHz references in compact form factors.

Oscillators Replacement Considerations

Public confirmed substitute part numbers include 7L-26.000MCN-T and 7L-26.000MCS-T. These are parameter-equivalent alternatives within the same manufacturer lineup. Verify pinout compatibility and exact electrical specifications before substitution.
