Low power components for 1 Gb/s optical communications: A single-chip 10-channel optical receiver and a clock recovery circuit

A single chip, 10-channel optical transimpedance receiver and a low-power, single channel clock recovery circuit have been designed and characterized. The 10-channel receiver operates from a single 3.3 V or 5 V power supply, is capable of automatic offset correction, and generates ECL or PECL output levels. The clock recovery circuit operates from a single 5 V power supply and is based upon a novel variation on the so-called early-late gate bit synchronizer loop.
