DS31415GN2

Overview

The DS31415GN2 is a single DPLL timing IC manufactured by Microchip Technology, housed in a 256-LBGA CSBGA package. It supports input frequencies up to 750MHz with CMOS or TTL inputs and provides CML, CMOS, LVDS, LVPECL, or TTL outputs. The device operates on a 1.8V supply voltage within an industrial temperature range of -40°C to +85°C. Designed for Ethernet, SONET/SDH, Stratum, and telecom applications, it features a 3:04 input-to-output ratio and supports differential signaling.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the 256-CSBGA (17x17) footprint matches the design requirements. Confirm that the 1.8V supply specification aligns with the target system power rails before procurement.

Selection Notes

Select this component when a single DPLL solution is required for high-frequency jitter cleaning or synthesis in telecom environments. The availability of multiple output formats allows flexibility in driving various downstream logic families. Verify that the 750MHz maximum frequency meets the system's clocking needs.

Part Context

This part belongs to the Application Specific Clock/Timing category under Microchip Technology. It is designed specifically for demanding synchronization tasks in network equipment. The 256-pin BGA package facilitates dense PCB layouts typical in modern telecommunications hardware.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Ensure any replacement maintains the 256-CSBGA pinout and 1.8V supply requirement to avoid redesign.
