DS3101GN

Overview

The DS3101GN is a Stratum 2/3E/3 timing card integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as an ATM/SONET/SDH support circuit designed for precise clock generation and synchronization in telecommunications networks. The device supports multiple input formats including CMOS, LVDS, LVPECL, and TTL, with corresponding output options of CMOS, LVDS, and TTL. It operates within a supply voltage range of 1.62V to 3.465V and features a maximum frequency of 311.04MHz. Encased in a 256-CSBGA package (17x17 mm), it is rated for industrial temperatures from -40°C to +85°C.
