Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm voltage and tolerance specifications. Ensure the component matches the required operating temperature range and load capacitance for the target design. Cross-reference the part number with authorized distributors to confirm authenticity and avoid counterfeit products.
Selection Notes
Select this component when a 20 MHz HCMOS clock source is required in a small form factor. Consider the 1.8V to 3.3V supply range compatibility with the system power rails. Evaluate the enable/disable feature if power management or clock gating is necessary for the application design.
Part Context
This oscillator belongs to the 1522H series from Suzhou Hangjing, which specializes in quartz frequency controlling units. The series offers various package sizes and frequencies for computing, automotive, and medical devices. Hangjing emphasizes low failure rates and professional pre-sales support for its piezoelectric crystal industry products.
Replacement Considerations
Compatible substitutes include other 20 MHz HCMOS oscillators in 4-SMD packages with similar voltage ranges. Verify pinout compatibility and electrical parameters before substitution. Check manufacturer datasheets for equivalent parts within the same product family.
