1208H-20.000G33DTSTK

Overview

The 1208H-20.000G33DTSTK is a standard HCMOS crystal oscillator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a nominal frequency of 20 MHz with a frequency stability of 50 ppm. The device utilizes a 3.3V supply voltage and features enable/disable functionality for power management. It is housed in an 8-DIP module package with 4 leads, designed as a half-size metal can component suitable for compact electronic applications requiring precise timing signals.

Feature Summary

• Integrated enable and disable control functions for efficient power management
• HCMOS output interface compatible with standard digital logic circuits
• Compact half-size metal can DIP packaging for space-constrained designs

Applications

• Embedded systems requiring precise clock synchronization
• Consumer electronics with limited board space
• Industrial control modules needing stable timing references

Procurement Notes

Verify the manufacturer part number against official Suzhou Hangjing documentation to confirm the specific 20 MHz frequency and 50 ppm stability rating. Ensure the 3.3V operating voltage aligns with your system design requirements. Confirm the 8-DIP package configuration matches your PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when a standard HCMOS output is required alongside low-power standby capabilities via the enable pin. The 50 ppm stability meets general timing needs but may not suit high-precision metrology applications. Consider the physical dimensions of the half-size metal can DIP package during layout planning to ensure adequate clearance and thermal management.

Part Context

This oscillator belongs to the 1208H series from Suzhou Hangjing, which specializes in quartz frequency control units. The series offers various frequencies and stability options, typically ranging from 25 to 100 ppm. The 1208H model line is designed for reliability in small form factor applications, leveraging metal can construction for environmental protection and signal integrity.

Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 3.3V HCMOS output, and 8-DIP half-size package. Verify that any alternative component supports the same enable/disable control logic and maintains comparable 50 ppm stability. Cross-reference pinouts and electrical characteristics to ensure functional compatibility without circuit redesign.
