- Integrated enable and disable control functionality
- Compact 4-SMD no-lead surface-mount packaging
Applications
- Consumer electronics devices
- Automotive electronic systems
- Industrial equipment timing circuits
Procurement Notes
Verify the complete part number including suffixes to ensure correct voltage and tolerance specifications. Confirm that the required operating temperature range aligns with the specific application environment. Check for any specific ordering suffixes that may indicate variations in tape and reel packaging or lead finish options before placing orders.
Selection Notes
Select this component when a 40 MHz clock signal is required with low voltage operation. The enable pin allows for dynamic power control, making it suitable for battery-operated applications. Ensure the host circuit supports HCMOS logic levels and can accommodate the small form factor of the 4-SMD package.
Part Context
This oscillator belongs to the 1521H series from Suzhou Hangjing, which focuses on quartz frequency control units. The series is characterized by tight stability and reliability, targeting applications in computing, communication, and medical devices where consistent frequency performance is critical.
Replacement Considerations
Direct substitutes must match the 40 MHz frequency, 1.8V supply, HCMOS output, and 4-SMD package dimensions. Verify that alternative components support the same enable/disable control feature and meet identical electrical specifications.
