18QHTF21-31.45728-PD is listed in the Oscillators range at ChipApex. The manufacturer field lists Mercury Electronics Ind. Co. Ltd. Its product description is 31.45728 MHz XO 1.8V 2.0X1.6 PD. Review the specifications below when checking this part for your BOM.
The 18QHTF21-31.45728-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a nominal frequency of 31.45728 MHz. It utilizes LVCMOS output logic and functions with a 1.8V supply voltage. The device features a standby or power-down capability for energy management. It is housed in a compact 4-SMD, no-lead package, suitable for surface-mount applications requiring precise timing signals.
Verify the specific frequency tolerance and load capacitance requirements against the target system design before procurement. Confirm that the 1.8V supply voltage aligns with the host controller's I/O levels. Ensure the 4-SMD no-lead package dimensions fit within the designated PCB footprint constraints to avoid assembly issues.
Select this component when a precise 31.45728 MHz reference is required alongside low-power standby capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 1.8V operating voltage as a primary constraint for power supply design. The compact SMD form factor aids in space-constrained layouts.
This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series typically offers various frequency options within a standardized 4-SMD package. The manufacturer specializes in quartz-based frequency control products, providing stable timing solutions for electronic assemblies.
Direct substitutes include other 31.45728 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical specifications such as supply voltage and output swing. Alternative models like 18QHTF21 variants with different frequencies are not electrically interchangeable.
