+3.3V, 622Mbps, SDH/SONET 1:4 Deserializer with LVDS Outputs
______________________________Features
o Single +3.3V Supply o 622Mbps Serial to 155Mbps Parallel Conversion o 265mW Power o LVDS Data Outputs and Synchronization Inputs o Synchronization Input for Data Realignment and Reframing o Differential 3.3V PECL Clock and Data Inputs
_________________General Description
T h e MAX3681 deserializer is ideal for converting 622Mbps serial data to 4-bit-wide, 155Mbps 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 low-voltage differential-signal (LVDS) clock and data outputs for interfacing with high-speed digital circuitry. It also provides an LVDS synchronization input that enables data realignment and reframing. The MAX3681 is available in the extended-industrial temperature range (-40°C to +85°C), in a 24-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.
