Oscillators datasheet and documents for 18QHTF21-44.960-PD
Oscillators Overview
The 18QHTF21-44.960-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 44.96 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a power-down standby function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.
Oscillators Feature Summary
- LVCMOS output logic interface
- Integrated power-down standby capability
- Compact surface-mount form factor
Oscillators Applications
- General clock signal generation
- Digital circuit timing reference
- Embedded system synchronization
Oscillators Procurement Notes
Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's specifications to ensure reliable operation and prevent frequency drift during power transitions or standby mode activation.
Oscillators Selection Notes
Select this component when a low-voltage 1.8V supply is available and space constraints require a small footprint. Ensure the application does not demand spread-spectrum functionality, as this model is specified as a standard oscillator. Verify compatibility with downstream logic levels accepting LVCMOS signals.
Oscillators Part Context
This part belongs to the Mercury Electronics 18QHTF series of surface-mount oscillators. The series typically offers various frequencies with standardized LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants within the same physical package family.
Oscillators Replacement Considerations
Direct substitutes must match the 44.96 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Check manufacturer datasheets for equivalent parts with identical pinout and electrical characteristics to ensure board-level compatibility without redesign.
