CW25-GDO-DK2-100.0M

Application Specific Clock/Timing Overview

The Connor Winfield CW25-GDO-DK2-100.0M is a GPS-based timing module within the CW25-GDO-DK series, designed for precise frequency synchronization. It integrates a TCXO with an onboard GPS receiver to provide stable clock outputs including CMOS, LVDS, and LVPECL. The device operates on a supply voltage of 2.97V to 3.63V and supports frequencies up to 700MHz. Housed in a 42-SMD surface-mount package, it functions reliably between -20°C and 70°C. This module combines timing generation with global positioning reference signals for high-accuracy applications.

Application Specific Clock/Timing Feature Summary

• Integrates GPS receiver with TCXO for autonomous time/frequency synchronization
• Provides multiple output interfaces: CMOS, LVDS, and LVPECL
• Supports maximum operating frequency of 700 MHz
• Operates within a supply voltage range of 2.97V to 3.63V

Application Specific Clock/Timing Applications

• Telecommunications base station synchronization
• Network infrastructure requiring precise timing references
• Test and measurement equipment needing stable frequency standards
• Navigation systems utilizing GPS-derived timing

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix DK2 against official Connor Winfield documentation to confirm pinout compatibility and functional differences from other variants in the CW25-GDO-DK series. Ensure the required output interface (CMOS, LVDS, or LVPECL) matches the target system design. Confirm that the 42-SMD package dimensions fit the PCB layout constraints.

Application Specific Clock/Timing Selection Notes

Select this module when both high-frequency stability and absolute time synchronization via GPS are required. Compare the 700MHz maximum frequency limit against system requirements. Evaluate the power consumption associated with the 2.97V–3.63V supply range. Consider the operating temperature range of -20°C to 70°C against environmental conditions.

Application Specific Clock/Timing Part Context

This component belongs to the CW25-GDO-DK series of GPS-based timing modules. Unlike standard VCXOs or OCXOs, this part includes an integrated GPS receiver to discipline the internal TCXO. It serves as a standalone solution for applications requiring both local stability and global time alignment without external timing sources.

Application Specific Clock/Timing Replacement Considerations

No direct public substitutes are identified. Alternative solutions may require separate GPS receivers and TCXOs, increasing board space and complexity. Verify if other suffixes in the CW25-GDO-DK family offer compatible form factors.
