The 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.
