Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Request the official datasheet from Mercury Electronics to validate electrical characteristics and reliability standards for the final application.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise frequency generation. The integrated enable/disable feature offers power efficiency benefits for battery-operated devices. The small 2.0x1.6 mm package is suitable for space-constrained designs. Ensure the LVCMOS output level is compatible with the receiving logic inputs of the connected microcontroller or FPGA.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies within a compact form factor. The suffix indicates specific frequency and package variations within the product line. Mercury Electronics has established manufacturing capabilities in quartz crystals since 1973.

Oscillators Replacement Considerations

Direct substitutes must match the 18.601 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications with alternative manufacturers such as Epson or NDK if sourcing changes are necessary.
