GENERAL DESCRIPTION
The Am7968 TAXIchip Transmitter and Am7969 TAXIchip Receiver Chipset is a general-purpose interface for very high-speed (4â17.5 Mbyte/s, 40â175 Mbaud serially) point-to-point communications over coaxial or fiber-optic media. The TAXIchip set emulates a pseudo-parallel register. They load data into one side and output it on the other, except in this case, the âotherâ side is separated by a long serial link.
