1553H-20.000E33AZSK

Overview

The 1553H-20.000E33AZSK is a standard HCMOS crystal oscillator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a frequency of 20 MHz and utilizes a 3.3V supply voltage. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package, designed for surface-mount applications in electronic circuits requiring precise clock signals.

Feature Summary

• Standard HCMOS output signal compatibility
• Integrated enable and disable control functionality
• Compact 4-SMD no lead surface-mount package design

Applications

• General-purpose digital circuit clocking
• Embedded system timing references
• Consumer electronics signal processing

Procurement Notes

Verify the exact operating temperature range and load capacitance requirements against your specific circuit design before procurement. Confirm that the 3.3V logic levels are compatible with your target interface. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Selection Notes

Select this component when a 20 MHz standard HCMOS clock source is required with low-power standby capabilities via the enable pin. Consider the 3.3V supply constraint and the physical dimensions of the 4-SMD package. Evaluate if the standard stability meets your system's jitter and phase noise requirements compared to higher-performance alternatives.

Part Context

This oscillator belongs to the 1553H series from Suzhou Hangjing Elec&Tech Co., Ltd., which focuses on quartz frequency control components. The company specializes in R&D and production of crystals and oscillators for various electronic sectors. This specific model represents a standard frequency solution within their portfolio of surface-mount devices.

Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 3.3V HCMOS output, and 4-SMD package. Verify equivalent enable/disable functionality and electrical characteristics. Cross-reference pinouts and thermal specifications to ensure compatibility without redesigning the host circuit.
