I538-2O7-20.000 MHZ

Oscillators Overview

The I538-2O7-20.000 MHZ is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by ILSI America. It operates at a nominal frequency of 20 MHz and utilizes a 3.0 V supply voltage. The device features an HCMOS output level within a compact 2.5 mm x 3.2 mm ceramic surface-mount package. Key electrical specifications include a maximum current consumption of 8 mA, a frequency stability of ±1.5 ppm over temperature, and a frequency tolerance of ±10 ppm at 25 °C. The component supports lead-free processing and RoHS compliance.

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the exact output format and frequency tolerance required for your design. Ensure that the procurement documentation explicitly states the RoHS and REACH compliance status. Confirm the active lifecycle status with the supplier prior to placing orders to mitigate obsolescence risks during production.

Oscillators Selection Notes

Select this component when a low-jitter clock source is required for high-speed digital interfaces. The HCMOS output level is suitable for standard logic families operating at 3.0 V. Consider the ±1.5 ppm stability requirement against your system's phase noise budget and timing constraints before finalizing the part selection.

Oscillators Part Context

This oscillator belongs to the I538 series of TCXOs from ILSI America. The series offers various frequency options and output formats. The I538-2O7 variant specifically denotes the 20 MHz frequency point with HCMOS output characteristics. It is designed for applications requiring precise timing in space-constrained environments.

Oscillators Replacement Considerations

Direct replacements may include other ILSI models within the same series offering identical pinouts and form factors. Verify that any substitute maintains the same 3.0 V supply requirement and HCMOS output swing to ensure circuit compatibility without redesign.
