18QHTF21-13.576-PD

Overview

The 18QHTF21-13.576-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.576 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby mode capability for power down functionality. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0mm by 1.6mm. This component serves as a precise timing source for digital circuits requiring stable clock signals.

Feature Summary

Provides stable LVCMOS clock signals at 13.576 MHz
Supports standby mode for power management
Compact surface-mount design suitable for space-constrained boards

Applications

Battery-powered portable devices
Digital signal processing systems
Communication equipment requiring precise timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable to maintain oscillator performance. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliability during assembly.

Selection Notes

Select this component when a 13.576 MHz clock is required with low voltage operation. Consider the LVCMOS output compatibility with downstream logic families. Evaluate the need for standby functionality if power conservation is critical. Compare size constraints against other available packages to confirm the 2.0x1.6mm form factor fits the layout.
