Oscillators Procurement Notes

Verify the exact part number suffix against manufacturer specifications to ensure correct package dimensions and electrical characteristics. Confirm that the supply voltage requirements align with the target circuit design, as this model supports both 1.8V and 3.3V operations. Check for compliance with environmental standards such as RoHS if required for the specific application region. Ensure that the load capacitance parameters match the system requirements for optimal frequency accuracy.

Oscillators Selection Notes

Select this component when a precise 18.432 MHz reference is required for digital logic interfaces. Consider the ±50 ppm stability specification for timing-sensitive applications. Evaluate the physical footprint constraints against the 4-pin SMD package dimensions. Verify that the enable pin functionality integrates correctly with the host controller's GPIO or power management strategy. Compare performance against alternative frequencies if the system architecture allows for flexibility.

Oscillators Part Context

This oscillator belongs to the S7 series of surface-mount devices from Aker Technology Corp. The series offers various standard frequencies optimized for digital communication protocols. The S73305T variant specifically denotes a 4-pin SMD package with lead-free construction.
