Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific environmental operating temperature ratings required for your application environment to ensure reliability.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS interface compatibility. The enable/disable feature allows for power management optimization in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify that the 29.44 MHz frequency meets the clocking needs of the target microcontroller or FPGA.

Oscillators Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronic. The series offers various frequencies and voltage options. The -OE suffix typically denotes specific packaging or tape-and-reel configurations. Mercury Electronic specializes in frequency control products including crystals, TCXOs, and VCTCXOs, providing reliable timing solutions for industrial and consumer electronics.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-29.790-OE, if frequency adjustment is permissible. Cross-brand replacements must match the 1.8V supply, LVCMOS output, and 4-SMD package dimensions precisely.
