I538-1R6-40.000MHZ

Oscillators Overview

The I538-1R6-40.000MHZ is a temperature-compensated crystal oscillator (TCXO) manufactured by ILSI. It operates at a nominal frequency of 40 MHz with CMOS output levels and a supply voltage of 2.5 V. The device features a frequency stability of ±3 ppm and draws a maximum supply current of 6 mA. Designed for surface-mount installation, it utilizes a 4-pin leadless SMD package. The operational temperature range spans from 0°C to 70°C.

Oscillators Feature Summary

• Temperature-compensated design ensures stable frequency performance across operating temperatures
• CMOS logic output levels compatible with standard digital interfaces
• Compact leadless surface-mount package facilitates automated assembly

Oscillators Applications

• Embedded systems requiring precise timing references
• Industrial automation equipment
• General electronics applications

Oscillators Procurement Notes

Verify the specific pinout configuration and mechanical dimensions against the official datasheet before integration. Confirm that the 2.5 V supply voltage aligns with the target circuit design. Ensure the 0°C to 70°C operating range meets environmental requirements. Cross-reference the leadless package type with PCB footprint specifications to prevent mounting errors during production.

Oscillators Selection Notes

Select this component when a low-cost TCXO solution is required for 40 MHz applications. The ±3 ppm stability offers improved accuracy over standard crystals without the complexity of OCXOs. Consider the 2.5 V supply constraint and 6 mA current draw for power budgeting. The leadless SMD form factor is suitable for space-constrained designs where standard packages are unavailable.
