535EL40005GT5

Oscillators Overview

The 535EL40005GT5 is a temperature-compensated crystal oscillator (TCXO) manufactured by CTS-Frequency Controls. It operates at a nominal frequency of 40 MHz with a stability of 0.5 ppm. The device utilizes a clipped sine wave output format and functions within a supply voltage range of 3.14 V to 3.47 V. Designed for surface mount applications, it features a compact 5.0 mm x 3.2 mm footprint with a height of 2 mm. The component supports an output enable function and maintains operational reliability across an extended industrial temperature range from -40°C to +105°C.

Oscillators Feature Summary

• Integrated temperature compensation ensures high frequency stability of 0.5 ppm across the operating range.
• Clipped sine wave output format provides signal integrity suitable for sensitive receiver inputs.
• Built-in output enable control allows for power management and system synchronization.

Oscillators Applications

• Wireless communication base stations requiring precise timing references
• High-performance GPS navigation systems
• Industrial test and measurement equipment

Oscillators Procurement Notes

Verify the specific suffix GT5 corresponds to the required reel quantity and tape configuration during procurement. Confirm that the supplier documentation explicitly lists the 0.5 ppm stability and clipped sine output for this exact part number. Ensure the ordering entity matches the manufacturer's official designation to avoid compatibility issues with automated assembly equipment.

Oscillators Selection Notes

Select this component when a low-profile surface mount TCXO is required for harsh thermal environments. The 0.5 ppm stability specification distinguishes it from standard XO devices. Consider the clipped sine output format against digital logic requirements; if CMOS levels are necessary, alternative series models may be more appropriate for direct interface without additional buffering.

Oscillators Part Context

This model belongs to the CTS Model 535 series of surface-mount TCXOs. The series is characterized by small form factors and wide temperature ranges. The 535EL variant specifically denotes the inclusion of an output enable pin and the use of a clipped sine wave output, differentiating it from other variants in the same physical package family.

Oscillators Replacement Considerations

Direct substitutes include other CTS 535 series parts with matching frequency and stability, such as the 535L40005GT5, provided the output format difference between clipped sine and HCMOS is acceptable for the circuit design.
