The MAX3881 deserializer with clock recovery is ideal for converting 2.488Gbps serial data to 16-bit-wide, 155Mbps parallel data for SDH/SONET applications. Operating from a single +3.3V supply, this device accepts high-speed serial-data inputs and delivers single-ended PECL parallel data outputs and a differential PECL parallel clock output for interfacing with digital circuitry.

The MAX3881 includes a low-power clock recovery and data retiming function for 2.488Gbps applications. The fully integrated phase-locked loop (PLL) recovers a synchronous clock signal from the serial NRZ data input; the signal is then retimed by the recovered clock. The MAX3881's jitter performance exceeds all SDH/SONET specifications. An additional 2.488Gbps serial input is available for system loopback diagnostic testing. The device also includes a TTL-compatible loss-of-lock (active-low LOL) monitor.

The MAX3881 is available in the extended temperature range (-40°C to +85°C) in a 64-pin TQFP-EP package.
