摘要
ＴＡＸＩ芯片 Ａｍ７９６８信号发送器和Ａｍ７９６９信号接收器是点对点通信，传输媒介为同轴点电缆或光缆的通用器件。其传输速率为４Ｍｂ／ｓ～１２．５Ｍｂ／ｓ，４０Ｍ～１２５Ｍ串行波特率。数据从一个端口输入，从另一个端口输出。ＴＡＸＩ芯片总线宽度灵活，可接收８、９、１０位宽的字节信号。多个ＴＡＸＩ芯片可以级连起来，以形成较宽的数据总线。所传送的字节可以是数据，也可以是指令。
The Taxi chip Am768 signal transmitter and Am769 signal receiver is a common device, which is used in communication of point to point. Its transmission medium can be either common cable or optical fiber. Its tiansmission rate can reach 4 - 12.5 Mb/s or 40 - 125 serial Band rate. The data are input at one port and output at another one. The bus width of the Taxi chip is flexible. It can be used in 8, 9 or 10 bit byte width, respectively. Multiple chips can be cascaded to form a wider data bus. The transmitted byte can be data or command.
