Procurement Notes
Verify the specific suffix 'PD' against the manufacturer's official datasheet to confirm lead time and availability status. Ensure the required operating temperature range matches the application environment. Confirm that the 4-SMD, No Lead package dimensions align with the PCB footprint design before finalizing procurement orders.
Selection Notes
Select this component when a 6.3 MHz clock source is required for digital logic interfacing. The 1.8V supply requirement makes it suitable for modern low-power systems. Consider the Enable/Disable feature if power management during standby modes is necessary for the target application design.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which specializes in quartz crystal oscillators. The series typically offers various frequencies and supply voltages. Mercury Electronics has been manufacturing frequency control products since 1973, establishing itself as a supplier in Taiwan.
Replacement Considerations
Cross-reference with other 6.3 MHz LVCMOS oscillators in 4-SMD packages. Verify pinout compatibility and electrical specifications such as supply current and load capacitance before substituting with components from different manufacturers.
