Overview
The 1521H-25.000G33DWSK is a standard HCMOS crystal oscillator manufactured by Suzhou Hangjing Elec & Tech Co., Ltd. It operates at a frequency of 25 MHz with a supply voltage range of 3.3V. The device features an enable/disable control function and is housed in a 4-SMD, no lead package. Key electrical specifications include a maximum supply current of 10 mA and frequency stability options of 30 ppm or 50 ppm.
Feature Summary
- HCMOS output interface for digital logic compatibility
- Enable and disable control functionality for power management
- Compact 4-SMD no-lead surface mount package design
Applications
- Automotive infotainment systems
- Automotive instrument clusters
- Industrial control equipment
Procurement Notes
Verify the specific frequency stability requirement (30 ppm vs 50 ppm) as both are listed for this part number. Confirm that the enable/disable pin configuration matches the system design. Ensure the 4-SMD no-lead footprint aligns with the PCB layout. Check the operating temperature range against application constraints. Validate the 3.3V supply voltage compatibility with the target circuit.
Selection Notes
Select this component when a 25 MHz clock signal with HCMOS output is required. The enable/disable feature makes it suitable for power-sensitive designs. Consider the 4-SMD package for space-constrained applications. Evaluate the stability requirements to determine if 30 ppm or 50 ppm is sufficient. Ensure the automotive or industrial environment meets the component's operational limits.
Part Context
This oscillator belongs to the quartz frequency control component family produced by Suzhou Hangjing Elec & Tech. The company specializes in R&D and manufacturing of crystals and oscillators for global electronics markets. This specific model is designed for high-reliability applications requiring precise timing signals in compact form factors.
Replacement Considerations
The related part 1521H-25.000G33DZSK offers standby power-down functionality instead of simple enable/disable. Verify if the additional power-down state is required for the application. Both parts share the same frequency, package, and output type.
