Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues or damage.

Selection Notes

Select this component when a precise 12.375 MHz reference is required in a small form factor. Consider the 1.8V operating voltage and LVCMOS interface compatibility with your target microcontroller or FPGA. The enable pin feature allows for dynamic power control, which is beneficial for battery-operated devices requiring extended standby times.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and packaging options. Mercury Electronic has been manufacturing frequency control products since 1973, specializing in quartz crystals and oscillators.

Replacement Considerations

Check for direct substitutes within the same series offering identical pinout and electrical characteristics. Verify that any replacement maintains the 1.8V supply requirement and LVCMOS output type. Ensure the physical footprint matches the 2.0x1.6mm SMD package to avoid PCB rework.
