DS3106LN2

Overview

The DS3106LN2 is a line card timing integrated circuit manufactured by Microchip Technology, designed for Ethernet, SONET/SDH, Stratum, and telecom applications. It features advanced DPLL technology within a single-circuit configuration. The device supports input formats of CMOS and TTL, while providing output options including CMOS, LVDS, LVPECL, and TTL. It operates with a maximum frequency of 312.5MHz and an input-to-output ratio of 2:2. Power supply requirements range from 1.62V to 1.98V, and it functions within a temperature range of -40°C to 85°C in a 64-LQFP (10x10) surface-mount package.

Feature Summary

• Advanced DPLL technology for precise timing
• Supports multiple output formats: CMOS, LVDS, LVPECL, TTL
• Single circuit with 2:2 input-to-output ratio
• Operates at frequencies up to 312.5MHz

Applications

• Ethernet network synchronization
• SONET/SDH timing systems
• Stratum clock applications
• Telecom infrastructure timing

Procurement Notes

Verify the specific ordering suffix 'LN2' against official Microchip documentation to confirm pinout, package dimensions, and material compliance details. Ensure the design accommodates the 1.62V to 1.98V supply voltage range and the 64-LQFP thermal requirements for the -40°C to 85°C operating environment.

Selection Notes

Select this component when a single-channel timing solution with flexible output drive capabilities is required for telecom or SONET/SDH environments. Confirm that the CMOS/TTL input compatibility matches the source clock interface and that the 312.5MHz maximum frequency meets the system's jitter cleaning or synthesis needs.

Part Context

This part belongs to the DS3106 family of line card timing ICs. It shares core architectural features with other variants in the series but is distinguished by its specific package type and electrical characteristics defined by the LN2 suffix. It serves as a specialized timing engine for high-reliability communication networks.

Replacement Considerations

Consult Microchip datasheets for direct cross-reference models within the DS3106 family. Verify functional equivalence regarding the 2:2 ratio, output formats, and supply voltage before substituting.
