MAX3681EAG

Serializers, Deserializers Overview

The MAX3681EAG is a +3.3V, 622Mbps SDH/SONET 1:4 deserializer with LVDS outputs manufactured by Analog Devices Inc./Maxim Integrated. It converts 622Mbps serial data to 4-bit-wide, 155Mbps parallel data for ATM and SDH/SONET applications. Operating from a single +3.3V supply, it accepts PECL serial clock and data inputs and delivers LVDS clock and data outputs. The device features an LVDS synchronization input for data realignment and reframing. It operates within the extended-industrial temperature range of -40°C to +85°C and is housed in a 24-pin SSOP package.
