- Low voltage digital circuit timing
- Embedded system clock sources
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your application needs before procurement. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Ensure the 4-SMD No Lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations if used in extreme environments.
Selection Notes
Select this component when a 6.5106 MHz clock source is required with LVCMOS outputs. Consider the 1.8V supply constraint and 21mA current draw during power budgeting. The small 2.0x1.6mm package is suitable for space-constrained designs. Evaluate the enable/disable feature if dynamic power control is necessary for the target application.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind. Co., Ltd. The manufacturer specializes in frequency control products including quartz crystals and oscillators. The series offers various frequencies within a standardized small outline package format, providing consistent mechanical and electrical characteristics across different model variants.
Replacement Considerations
Direct substitutes may include other 6.5106 MHz LVCMOS oscillators in 4-SMD packages with compatible 1.8V operation. Verify pinout compatibility and electrical specifications such as current consumption and output swing before substitution.
