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.
The MAX3680/MAX3680A is a 1:8 deserializer that converts 622 Mbps serial data to 8‑bit parallel data for SDH/SONET and ATM applications. It operates from a single +3.3 V supply and offers TTL outputs with an optional synchronization input for data realignment.
Key features include a 622 MHz maximum serial‑clock frequency, 165 mW power consumption, differential PECL inputs, and a 28‑pin SSOP package that is rated for -40 °C to +85 °C operation. The datasheet details pin functions, electrical characteristics, layout recommendations, and package dimensions.
