MAX3873AETP+

Overview

The MAX3873AETP+ is a SONET/SDH Clock and Data Recovery (CDR) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. Designed for high-speed optical communication, it operates at frequencies up to 2.67Gbps with a single circuit configuration. The device accepts CML differential inputs and provides CML differential outputs in a 1:2 ratio. It functions within a supply voltage range of 3V to 3.6V and includes an internal Phase-Locked Loop (PLL). Packaged in a 20-TQFN (4x4) surface-mount case with an exposed pad, it supports an operating temperature range from -40°C to +85°C.
