I537-2O7-25.000 MHZ

Oscillators Overview

The I537-2O7-25.000 MHZ is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by ILSI America, operating at a nominal frequency of 25 MHz. It utilizes a clipped sine wave output with a minimum amplitude of 0.8 V p-p and features a 4-SMD, No Lead package. The device operates within a supply voltage range of 1.5 VDC to 3.3 VDC, drawing a maximum current of 2 mA. It provides high frequency stability of ±1 ppm at +25°C and an aging rate of ±1 ppm per year maximum. The unit supports control voltages from ±1.0 VDC for temperature compensation and functions reliably across an extended industrial temperature range of -40°C to +85°C.

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official part number guide to ensure correct temperature range and output specifications. Confirm that the required supply voltage aligns with the selected variant's tolerance limits. Check for RoHS compliance documentation if environmental regulations apply to your assembly process. Ensure the footprint matches the 4-SMD, No Lead package dimensions provided in the mechanical drawings. Validate that the control voltage requirements match your system's compensation interface capabilities before finalizing procurement.

Oscillators Selection Notes

Select this component when a balance of high frequency stability and low power consumption is critical. The wide operating temperature range makes it suitable for harsh environments where standard oscillators might fail. Consider the clipped sine wave output compatibility with your downstream logic circuits. Evaluate the need for external temperature compensation versus integrated solutions based on board space constraints. Compare aging rates against long-term drift requirements for your specific application timeline.
