Description
The 854S712I is a differential, high-speed 1:2 data/clock fanout buffer and line driver. 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 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 4.5 Gbps (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. Internal input termination, a bias voltage output for AC-coupling and small packaging (VFQFN) supports space-efficient board designs. The 854S712I operates from a 3.3V power supply and supports the industrial temperature range of -40°C to +85°C.

Using 854S712I for 4.5 Gbps Applications with Pre-Emphasis
Yes, the part can still be used for 4.5 Gbps applications. In this case, the pre-emphasis will take place only as long as the signal is high or low( i.e. approx. 111 ps). For other questions not addressed by the knowledge base, please submit a technical support ...
