19-1210; Rev 0; 3/97 KIT ATION EVALU LE B A IL A AV +3.3V, 622Mbps, SDH/SONET 1:8 Deserializer with TTL Outputs ______________________________Features o Single +3.3V Supply o 622Mbps Serial to 77Mbps Parallel Conversion o 165mW Power o Synchronization Input for Data Realignment and Reframing o Differential 3.3V PECL Clock and Data Inputs o TTL Data Outputs and Synchronization Input _________________General 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.
