AD802-155KR

Overview

The AD802-155KR is a Phase Locked Loop (PLL) frequency synthesizer from Analog Devices Inc., designed for DS-3 and STS-1 applications. It operates with ECL input and output levels, supporting a maximum frequency of 155.52 MHz. The device functions within a supply voltage range of 4.5 V to 5.5 V and is rated for an operating temperature range of 0°C to 70°C. Packaged in a 20-SOIC case, it serves as a dedicated timing solution for specific telecommunications standards.

Feature Summary

• Designed for DS-3 and STS-1 main-purpose applications
• Operates with ECL input and output signal levels
• Maximum frequency capability of 155.52 MHz
• Supply voltage range of 4.5 V to 5.5 V

Applications

• DS-3 telecommunications systems
• STS-1 network infrastructure
• Frequency synthesis for 155.52 MHz clock generation

Procurement Notes

Verify the package type matches the 20-SOIC specification. Confirm the operating temperature range meets the 0°C to 70°C requirement. Ensure the system supports ECL logic levels for both input and output interfaces. Check supply voltage compatibility within the 4.5 V to 5.5 V range before integration.

Selection Notes

Select this component when DS-3 or STS-1 compliance is required. The ECL interface dictates compatible driver and receiver circuits. The 155.52 MHz limit defines the maximum operational speed. The industrial temperature range must align with the environmental conditions of the target application.

Part Context

This part belongs to the Application Specific Clock/Timing category. It is a specialized PLL unit rather than a general-purpose synthesizer. The design focuses on fixed-frequency generation for standard digital hierarchy rates.
