4-16 Gb/s Rate-Selectable Transimpedance Amplifier

Overview

The GN1068 is an extended-capability transimpedance amplifier die. The GN1068 is user configurable for desired bit rate, where the nominal rates supported are Fibre Channel 14.025Gb/s and 8.5/4.25Gb/s rates, as well as the 10 Gigabit Ethernet rate of 10.3125Gb/s. Selection of the rate optimizes the noise performance for operation at that rate.
The GN1068 design is implemented such that electro-optic gain is well controlled for maximum RF stability in the user's package. The GN1068 is intended to offer careful RF matching of photodiode and TIA for optimized performance.
