Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V enable pin logic aligns with your system's control voltage levels. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to avoid assembly issues during production.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 16.992 MHz applications. Consider the LVCMOS output type if interfacing directly with digital logic inputs without additional buffering. Evaluate the enable/disable feature necessity for power-sensitive designs where idle state current reduction is critical for battery life or thermal management.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. Mercury has been a pioneer in Taiwan's crystal industry since 1973, offering various oscillators and resonators.
