I538-2O7-39.000 MHZ

Oscillators Overview

The I538-2O7-39.000 MHZ is a temperature-compensated crystal oscillator (TCXO) manufactured by ILSI. It provides a stable 39 MHz output signal with an HCMOS logic interface. The device operates on a single 3V power supply and draws a maximum current of 6mA. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount assembly. The component supports an operating temperature range from -40°C to 85°C, ensuring reliable performance across various industrial environments.

Oscillators Feature Summary

• Temperature-compensated crystal oscillator design for frequency stability
• HCMOS output interface compatible with standard digital logic
• Low power consumption with 3V operation and 6mA max current draw

Oscillators Applications

• Embedded systems requiring precise clock signals
• Industrial automation equipment
• General electronics applications needing stable timing references

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 39 MHz specification. Confirm that the 4-SMD no-lead package footprint aligns with the PCB layout. Ensure the 3V supply voltage and HCMOS output levels are compatible with the target circuit design before finalizing procurement.

Oscillators Selection Notes

Select this component when a stable 39 MHz reference is needed in space-constrained designs. The TCXO technology compensates for temperature variations, making it suitable for environments with fluctuating thermal conditions. The low profile SMD package facilitates automated assembly processes.

Oscillators Part Context

This part belongs to the ILSI I538 series of TCXOs. Variants within this series offer different frequencies such as 16 MHz, 25 MHz, 27 MHz, and 32 MHz. All share similar electrical characteristics including 3V operation and HCMOS outputs, differing primarily in their nominal output frequency specifications.

Oscillators Replacement Considerations

Direct substitutes include other ILSI I538 series parts with identical pinouts and electrical profiles but different frequencies, provided the system can tolerate the frequency change. Cross-brand replacements require verification of pin compatibility, voltage levels, and phase noise specifications.
