3.3V, 622Mbps, SDH/SONET 1:8 Deserializer with TTL Outputs

The MAX3680/MAX3680A 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. The MAX3680 also provides a TTL synchronization input that enables data realignment and reframing.

The MAX3680/MAX3680A is available in the extended-industrial temperature range (-40°C to +85°C), in a 28-pin SSOP package.
