Oscillators datasheet and documents for 18QHTF21-22.000-PD
Oscillators Overview
The 18QHTF21-22.000-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 22 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a power-down standby function to reduce consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.
Oscillators Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Includes power-down standby functionality for energy efficiency
- Utilizes a surface-mount 4-SMD no-lead package design
Oscillators Applications
- General-purpose clock signal generation
- Digital circuit timing references
- Embedded system clock sources
Oscillators Procurement Notes
Verify the specific operating temperature range and load capacitance requirements against the target application's datasheet specifications. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the 2.0x1.6mm footprint matches the PCB layout constraints before finalizing procurement decisions.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a compact 2.0x1.6mm form factor. The LVCMOS output is suitable for standard digital logic families. Consider the power-down feature if system-level energy management is a priority for the specific electronic design.
Oscillators Part Context
This part belongs to the Mercury Electronics XO series, characterized by small SMD packages and standard frequency options. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from continuously active variants within the same physical footprint family.
Oscillators Replacement Considerations
Cross-reference other 18QHTF21 series parts with identical 2.0x1.6mm footprints and 1.8V LVCMOS outputs. Verify that substitute models support the same power-down functionality and frequency stability requirements.
