GENERAL DESCRIPTION
The Am7968 TAXIchip Transmitter and Am7969
TAXIchip Receiver Chipset is a general-purpose inter-
face for very high-speed (4–17.5 Mbyte/s, 40–175
Mbaud serially) point-to-point communications over co-
axial 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 “other”
side is separated by a long serial link.
The speed of a TAXIchip system is adjustable over a
range of frequencies, with parallel bus transfer rates of
4 Mbyte/s at the low end, and up to 17.5 Mbyte/s at the
high end. The flexible bus interface scheme of the
TAXIchip set accepts bytes that are either 8, 9, or
10 bits wide. Byte transfers can be Data or Command
signaling.
