2:1 Multiplexer And 1:2 Demultiplexer With Pre-Emphasis

The 854S713I is a differential, high-speed 2:1 data/clock multiplexer and 1:2 clock/data demultiplexer in one device. The outputs support pre-emphasis in order to drive backplanes and long transmission lines while reducing inter-symbol interference effects. The pre-emphasis level is individually configurable to optimize for low bit error rate or power consumption. Pre-emphasis utilizes an increased output voltage swing for transition bits. The device is optimized for data rates up to 4.5Gbps (NRZ) and for deterministic jitter in data applications and low additive jitter in clock applications. The outputs are LVDS-compliant while the differential input is compatible with a variety of signal levels such as LVDS, LVPECL and CML. A small package (4.0mm x 4.0mm 24-lead VFQFN) supports space-efficient board designs. The 854S713I operates from a 3.3V power supply and supports the industrial temperature range of -40 to +85 deg C.
