MAX3680 Datasheet | Maxim Integrated

Description The MAX3680 deserializer is ideal for converting 622Mbps serial data to 8-bit-wide, 77Mbps parallel data in ATM and SDH/SONET applications. Operating from a single +3.3V supply, this device accepts PECL serial-clock and data inputs, and delivers TTL clock and data outputs. It also provides a TTL synchronization input that enables data realignment and reframing. The MAX3680 is available in the extended-industrial temperature range (-40°C to +85°C), in a 28-pin SSOP package. __________________________Applications 622Mbps SDH/SONET Transmission Systems 622Mbps ATM/SONET Access Nodes Add/Drop Multiplexers Digital Cross Connects PART MAX3680EAI TEMP.
