Overview
The 18QHTF21-59.075833-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 59.075833 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- Supports standby mode for power reduction
- Utilizes LVCMOS output interface
- Compact no-lead surface mount design
Applications
- General digital circuit timing
- Embedded system clock generation
- Communication equipment synchronization
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply rail stability meets the component's operational specifications to ensure signal integrity. Ensure the PCB layout accommodates the 4-SMD no-lead package dimensions accurately.
Selection Notes
Select this component when a fixed 59.075833 MHz frequency is required with low-power standby capabilities. The LVCMOS output is suitable for standard logic interfaces. Consider the 1.8V operating voltage constraint and the physical footprint of the 4-SMD package during the design phase to ensure compatibility with the target application board.
Part Context
This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'PD' suffix typically indicates the presence of a power-down or standby control feature, distinguishing it from models without such functionality.
Replacement Considerations
Direct substitutes must match the 59.075833 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics with alternative manufacturers' components to ensure functional equivalence.
