A 5.28-Gb/s serializer ASIC for uncompressed long-haul multimedia interconnects

Abstract

We report a 5.28-Gb/s serializer ASIC for uncompressed long-haul video interconnects. Our ASIC is based on the serializer architecture which maintains the constant output data rate for various resolutions of incoming video signals from VGA to UXGA. With this, a wide-band phase-locked-loop in a serializer and a continuous-rate clock-and-data-recovery circuit in a de-serializer are not necessary. The serializer ASIC contains clock-and-data-recovery circuits, de-multiplexers, a digital processing block, a phase-locked-loop, multiplexers. A VCSEL driver circuit is also integrated so that it can be used for long-haul transmission with multimode fiber. The ASIC produces 5.28-Gb/s serialized driving currents for VCSEL from parallel input signals. It occupies 3.45 mm2 and consumes 151.7 mW.
