Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate the enable/disable pin configuration with your schematic to ensure proper operation.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for high-frequency precision timing. Consider the small 2.0x1.6 mm package size for dense board layouts. Evaluate the enable/disable feature if power conservation is critical. Compare stability specifications against other available frequencies if 18.33111 MHz is not strictly necessary. Ensure compatibility with existing CMOS logic families in the target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within the LVCMOS format. Mercury Electronic Industrial Co., Ltd. has a long history in quartz crystal manufacturing, providing frequency control products including crystals and oscillators.
