I537-2O7-26.000 MHZ

Oscillators Overview

The I537-2O7-26.000 MHZ is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by ILSI America. It operates at a nominal frequency of 26 MHz with a clipped sine wave output level of 0.8 V p-p minimum into a 20K Ohms / 10 pF load. The device supports a supply voltage range typically centered around 3V DC with a maximum current consumption of 2 mA. It features a frequency stability of ±1 ppm at +25°C and an aging rate of ±1 ppm per year maximum. The component is housed in a surface-mount ceramic package measuring 2.5 mm x 3.2 mm, designed for operation within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Integrated temperature compensation for high frequency stability across wide operating ranges
• Ultra-miniature surface-mount ceramic package suitable for space-constrained designs
• Low power consumption profile optimized for battery-operated applications
• Compliant with lead-free processing standards for environmental safety

Oscillators Applications

• Wireless communication systems requiring precise clocking
• Portable electronic devices with limited power budgets
• Industrial control equipment operating in variable thermal environments
• Telecommunications infrastructure components

Oscillators Procurement Notes

Verify the specific suffix codes against official ILSI documentation to confirm exact frequency tolerance and temperature grade specifications. Ensure compatibility with reflow soldering profiles specified in the datasheet. Confirm that the required frequency stability meets system timing requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a compact TCXO solution is needed for 26 MHz applications requiring ±1 ppm stability. Consider the 2.5mm x 3.2mm footprint for PCB layout constraints. Evaluate the 2 mA current draw against total system power budgets. Verify that the clipped sine output interface matches the receiving circuit input requirements.

Oscillators Part Context

This oscillator belongs to the I537 series from ILSI America, which offers various frequency options within the 12 MHz to 27 MHz range. The series utilizes AT-cut crystals for superior frequency stability compared to standard crystal oscillators. The I537 designation specifically indicates a TCXO variant, distinguishing it from the I737 TCVCXO series which includes voltage control capabilities.

Oscillators Replacement Considerations

Direct replacements must match the 26 MHz frequency, 2.5x3.2mm package, and clipped sine output. Check equivalent TCXOs from other manufacturers for similar ±1 ppm stability and -40°C to +85°C operating ranges. Ensure pinout compatibility if substituting with different package styles.
