Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required voltage levels and load conditions. Confirm that the 4-SMD no-lead package matches the footprint specifications of the target PCB design. Check for any recent revisions to the enable/disable pin configuration or electrical characteristics before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 14.4756 MHz reference is required for low-power embedded systems. Ensure the design accommodates the 3.3V supply requirement and the physical constraints of the 2.0x1.6mm package. Consider the LVCMOS drive strength requirements of the receiving circuitry to guarantee signal integrity across the operating temperature range specified in the official documentation.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic. The series offers various frequency options within a standardized small outline package format. These components are typically used as primary clock sources in consumer electronics and industrial control modules where reliable frequency stability and minimal board space are critical design factors.

Oscillators Replacement Considerations

Direct substitutes must match the 14.4756 MHz frequency, 3.3V operation, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical parameters such as jitter and phase noise against the original specification sheet before implementing any alternative source.
