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 power management scheme. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your environmental conditions.

Selection Notes

Select this oscillator when a low-voltage 1.8V operation is required alongside LVCMOS interface compatibility. The small 2.0x1.6mm form factor makes it suitable for space-constrained designs. Consider the enable/disable feature if power management during idle states is a priority. Verify that the 10.4857 MHz frequency meets the specific data rate or clocking needs of the target application without requiring external dividers.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on quartz crystal oscillators. The manufacturer is a specialized supplier of frequency control products including crystals and filters. The series typically offers various frequencies and package options to support diverse electronic timing requirements across consumer and industrial electronics markets.

Replacement Considerations

Direct substitutes must match the 10.4857 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as phase noise and jitter before substitution. Cross-reference with other manufacturers offering similar surface-mount oscillators if availability is an issue.
