18QHTF21-31.61388-OE is listed in the Oscillators range at ChipApex. The manufacturer field lists Mercury Electronics Ind. Co. Ltd. Its product description is 31.61388 MHz XO 1.8V 2.0X1.6 OE. Review the specifications below when checking this part for your BOM.
The 18QHTF21-31.61388-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 31.61388 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper soldering and mechanical stability during assembly.
Select this component when a precise 31.61388 MHz timing source is required for low-power digital applications. The LVCMOS output ensures compatibility with standard logic families operating at 1.8V. Consider the enable/disable feature if dynamic power saving is necessary. Verify that the operating temperature range meets the environmental conditions of the intended deployment scenario.
This part belongs to the standard XO series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in quartz frequency control products. The model number indicates a specific frequency variant within their SMD oscillator lineup. Mercury Electronics has a history of producing quartz crystals and oscillators, positioning this component as a standard timing solution for consumer and industrial electronics.
Direct substitutes must match the 31.61388 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if critical. Cross-reference with other manufacturers' equivalent parts ensuring identical form factor and functional parameters.
