+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
T h e MAX3680 deserializer is ideal for converting 6 2 2 M b p s 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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
