Functional Description

The TC9021/TC9020 is part of a new generation of high performance, host-optimized network interface cards designed for mission critical systems such as servers and high-end workstations. Offering two gigabits per second of aggregate bandwidth, the TC9021/TC9020 optimizes performance while minimizing network overhead on the host system. Compared to leading Fast Ethernet solutions, the TC9021/TC9020 transfers data at less than one tenth of the host CPU utilization rate.
