The 1521H-25.000GWVDZSK is a standard crystal oscillator manufactured by Suzhou Hangjing Elec & Tech Co., Ltd. It operates at a frequency of 25 MHz and utilizes HCMOS output logic levels. The device supports an operating voltage range from 1.8V to 3.3V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.
Verify the manufacturer designation as Suzhou Hangjing Elec & Tech Co., Ltd. when sourcing this component. Confirm that the specific suffix ZSK corresponds to the required packaging and tape-and-reel specifications for your assembly line. Ensure the HCMOS logic level matches your system's input requirements before procurement.
Select this model when a 25 MHz clock source with HCMOS output is required. Consider the 1.8V to 3.3V voltage range for compatibility with low-power digital circuits. The enable/disable feature makes it suitable for battery-operated devices requiring power conservation. Verify the 4-SMD footprint fits your PCB layout constraints.
