Overview
The 18QHTF21-100.100-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 100.1 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage power consumption during inactive periods. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount applications requiring precise timing signals.
Feature Summary
- Integrates LVCMOS output interface for digital signal compatibility
- Supports standby mode via power-down control pin
- Utilizes quartz crystal technology for frequency stability
Applications
- Digital clock generation in embedded systems
- Timing reference for microprocessors
- Communication interface synchronization
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6 mm footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to maintain component integrity during assembly.
Selection Notes
Select this model when a 100.1 MHz clock source is required with low voltage operation. Consider the LVCMOS output swing if interfacing with 1.8V logic families. Evaluate the need for power-down functionality if energy efficiency is critical. Compare package size against available board space. Verify temperature range specifications if operating in extreme environmental conditions.
Part Context
Mercury Electronic Ind. Co., Ltd. is a manufacturer specializing in frequency control products, including quartz crystals and oscillators. The company has decades of experience in the industry, focusing on precision timing components. This part belongs to their series of surface-mount crystal oscillators designed for consumer and industrial electronics.
Replacement Considerations
Direct substitutes must match the 100.1 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Cross-reference with other manufacturers offering similar XO specifications. Ensure electrical parameters such as phase noise and jitter are compatible with the original design requirements.
