- Enable/Disable control pin
- Compact SMD form factor
Applications
- General-purpose digital timing circuits
- Embedded system clock sources
- Consumer electronics timing references
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 4-SMD package footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The enable/disable feature makes it suitable for battery-powered devices needing power optimization. Consider the 6.48955 MHz frequency specifically if your application requires this exact timing reference rather than standard integer frequencies.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in Taiwan producing crystals and oscillators. This series represents their standard surface-mount oscillator offerings designed for reliable performance in various electronic assemblies.
Replacement Considerations
Direct substitutes must match the 6.48955 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before swapping. Consult distributor databases for cross-reference lists provided by Mercury Electronics or third-party equivalents.
