Oscillators Procurement Notes

Verify the specific frequency stability requirement (±50 ppm or ±25 ppm) against the application needs, as both variants exist within the S7 series. Confirm that the 1.544 MHz nominal frequency matches the system design specifications. Ensure the 4-pin SMD package dimensions align with the target PCB footprint. Check for RoHS compliance documentation if required by regulatory standards.

Oscillators Selection Notes

Select this component when a precise 1.544 MHz HCMOS clock source is required for telecommunications or data transmission applications. Consider the ±50 ppm or ±25 ppm stability options based on jitter tolerance requirements. The wide supply voltage range allows integration with various logic families. Evaluate thermal performance if the device will operate near the upper limit of the -40°C to +85°C range.

Oscillators Part Context

This oscillator belongs to the Aker S7 series, which offers a broad range of frequencies and stability options in standard surface-mount packages. The S733025T variant specifically targets low-frequency precision applications. It competes with other industry-standard HCMOS oscillators providing similar form factors and electrical characteristics for embedded timing solutions.

Oscillators Replacement Considerations
