Overview

The GN2412 Family is a twelve -lane retimer with adaptive equalization and transmit de-emphasis designed for 5Gbps to 12.8Gbps of full rate operations. It is also designed for half-rate and quarter-rate operation to retime down to 1.25Gbps, Ethernet, Infiniband and Fiber Channel applications. The GN2412 Family extends the reach and robustness of high-speed serial links by compensating for losses and reflections in the transmission medium, and by resetting the crosstalk and jitter budgets.
