Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the exact frequency tolerance and output configuration matches the design requirements. Ensure the procurement source provides valid manufacturer documentation to confirm the component's active status and compliance with lead-free processing standards. Cross-reference the package dimensions and pinout with the official datasheet to guarantee compatibility with the intended PCB footprint.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount TCXO is required for 25 MHz applications. The 3V supply voltage makes it suitable for modern low-power digital circuits. Consider the ±1.5ppm stability specification against system jitter requirements. Verify that the CMOS output level aligns with the input voltage thresholds of the downstream clock receiver to ensure signal integrity without additional buffering.

Oscillators Part Context

This part belongs to the ILSI I538 series of Surface Mount TCXOs. The series offers various frequency options within the 8 MHz to 30 MHz range. These oscillators are designed for high-performance applications demanding low jitter and non-PLL based outputs. The I538 series is compatible with both clipped sinewave and HCMOS output levels, providing flexibility for different interface requirements in telecommunications and computing hardware.

Oscillators Replacement Considerations

Direct substitutes include other ILSI I538 series variants with matching 25 MHz frequencies and 3V operation. Check for equivalent TCXOs from other manufacturers offering identical 3.20mm x 2.50mm packages and CMOS outputs. Ensure any replacement maintains the -40°C to +85°C operating temperature range and similar stability specifications to avoid system performance degradation.
