18QHTF21-33.178-PD is listed in the Oscillators range at ChipApex. The manufacturer field lists Mercury Electronics Ind. Co. Ltd. Its product description is 33.178 MHz XO 1.8V 2.0X1.6 MM PD. Review the specifications below when checking this part for your BOM.
The 18QHTF21-33.178-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 33.178 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down capability. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6mm. This component is designed for applications requiring precise timing signals within low-power electronic systems.
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues during manufacturing.
Choose this model when a 33.178 MHz clock source is required with low voltage operation. Consider the LVCMOS output level if interfacing with standard CMOS logic families. Evaluate the need for power-down functionality to optimize energy consumption in battery-operated devices compared to continuous oscillation alternatives.
This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a small form factor. The series typically provides standard XO performance with integrated power management features. It serves as a timing reference solution for compact electronic designs requiring reliable frequency generation.
Direct substitutes include other 18QHTF21 variants with different frequencies such as 18QHTF21-51.200-PD or 18QHTF21-6.000-PD, provided the frequency difference is acceptable for the application.
