DS3100GN

Overview

The DS3100GN is a timing line card integrated circuit manufactured by Microchip Technology, designed for ATM/SONET/SDH support circuits. It operates within a supply voltage range of 1.62V to 1.98V and supports an operating temperature range of -40°C to 85°C. The device features a single circuit with a frequency maximum of 311.04MHz and utilizes a 256-LBGA CSBGA package measuring 17x17 mm. It accepts CMOS, LVDS, LVPECL, or TTL inputs and provides CMOS, LVDS, or TTL outputs. Key specifications include a 14:11 input-to-output ratio and built-in PLL functionality.

Feature Summary

• Supports ATM/SONET/SDH applications with Stratum and Telecom main purposes
• Features internal PLL for precise clock generation
• Offers flexible I/O options including CMOS, LVDS, LVPECL, and TTL
• Operates at frequencies up to 311.04MHz

Applications

• Ethernet network synchronization
• SONET/SDH line interface units
• Telecom infrastructure timing distribution
• Stratum level clocking systems

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct package type and temperature grade. Confirm that the 256-CSBGA (17x17) footprint matches the target PCB design. Check for any recent lifecycle status changes such as obsolescence or transfer notices from the manufacturer.

Selection Notes

Select this component when designing SONET/SDH line cards requiring a 14:11 ratio conversion. Ensure the power supply can maintain the 1.62V to 1.98V range under all load conditions. Verify that the required input/output signal standards (CMOS/LVDS/LVPECL/TTL) are compatible with the system architecture.

Part Context

This part belongs to the category of Application Specific Clock/Timing devices. It is distinct from general-purpose oscillators as it includes specific logic for telecom protocols like SONET/SDH. The 256-pin BGA package indicates a high-density interconnect solution suitable for complex digital signal processing environments.
