Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage, frequency, and package configuration. Confirm that the supplier provides traceability documents matching the part number 1575H4-25000K33DTSK. Check for any recent updates to the datasheet regarding environmental compliance or pinout definitions before finalizing procurement orders.
Selection Notes
Select this component when a 25 MHz timing source with HCMOS output is required. Ensure the system design supports a 3.3V supply rail. Consider the ±10ppm stability requirement against the application's jitter tolerance. Verify that the 4-SMD footprint matches the PCB layout constraints and that the enable/disable feature aligns with power sequencing requirements.
Part Context
This part belongs to the 1575H4 series of standard crystal oscillators from Suzhou Hangjing. The series integrates quartz resonators with CMOS driver circuits in small form factors. The manufacturer specializes in frequency control components, offering various XO, TCXO, and VCXO products for industrial and consumer electronics markets.
Replacement Considerations
Direct replacements must match the 25 MHz frequency, 3.3V HCMOS output, and 4-SMD package. Verify pin-to-pin compatibility and electrical specifications such as current consumption and load capacitance. Cross-reference with other manufacturers' 25MHz HCMOS oscillators ensuring identical envelope dimensions and mounting characteristics.
