Semtech GN1068
4-16 Gbps 可选配速率的跨阻放大器
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 14.025Gbps and 8.5/4.25Gbps rates, as well as the 10 Gigabit Ethernet rate of 10.3125Gbps. 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.
