DS3100GN2

Overview

The DS3100GN2 is a Stratum timing integrated circuit manufactured by Microchip Technology, designed for Ethernet, SONET/SDH, and telecom applications. It features a single PLL circuit with differential input and output capabilities. The device supports a maximum frequency of 311.04MHz and operates on a supply voltage ranging from 1.62V to 1.98V. Input interfaces include CMOS, LVDS, LVPECL, and TTL, while outputs support CMOS, LVDS, and TTL. It is housed in a 256-CSBGA (17x17) package and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Stratum-compliant timing IC for Ethernet and SONET/SDH networks
• Single PLL circuit with 14:11 input-to-output ratio
• Supports differential inputs and outputs for signal integrity
• Operates at frequencies up to 311.04MHz

Applications

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

Procurement Notes

Verify the specific ordering suffix 'GN2' against official Microchip documentation to confirm pinout, packaging, and RoHS compliance details. Ensure compatibility with the required 256-CSBGA footprint and 1.62V-1.98V power domain during procurement planning.

Selection Notes

Select this component when a Stratum-level clock solution is required for SONET/SDH or Ethernet applications. Confirm that the 311.04MHz maximum frequency meets system requirements and that the 256-pin CSBGA package fits the PCB layout constraints.

Part Context

This part belongs to the DS3100 series of application-specific clock and timing ICs. It is distinct from other models like the DS31400 or DS31406, which may offer different I/O ratios or frequency ranges. The GN2 suffix typically denotes specific packaging or environmental qualifications within the Microchip portfolio.

Replacement Considerations

Check for direct replacements such as the DS3100GN+ or updated revisions within the DS3100 family. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
