Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against your system requirements before procurement. Ensure the 1.8V supply voltage aligns with your target circuit design. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues or damage.

Oscillators Selection Notes

Select this component when a precise 28.88 MHz clock source is required in a minimal footprint. The 1.8V operation makes it suitable for modern low-power applications. Consider the enable pin requirement if dynamic power saving is necessary. Verify that the 4-SMD no-lead package matches your PCB layout constraints and soldering capabilities.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, designed for high-performance timing applications. The series typically offers various frequencies within a small form factor. The 'OE' suffix indicates the inclusion of an output enable feature, distinguishing it from basic oscillator variants without control pins.

Oscillators Replacement Considerations

Direct substitutes must match the 28.88 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Check datasheets for equivalent parts from other manufacturers offering identical electrical characteristics and pinout configurations to ensure seamless integration.
