TAXIchip Integrated Circuits Technical Manual
Jumpers are provided on the outputs of Q4 and Q5 to be inverted (U7) and fed back to
the first NAND gate (U1). If Q4 is shorted back to the strobe input, the system will run in
auto-repeat ACK 0mode. This means that there will be a strobe on every clock cycle. In
this mode a sync will never be sent. If the output of Q5 is shorted back to the strobe
input, the system will run in auto-repeat ACK 1 mode. This means that a sync will be
automatically inserted in between each group of four data bytes.
On the receiver end of the link, the option is left up to the designer to either use four
Am7969 TAXI Receivers or to demultiplex the data and use only one Receiver.
Figure 16 has been included to give a detailed schematic of the circuit with an Am7969
TAXI Receiver on-board to complete the data path. Figures 17, 18, and 19 show typical
outputs for auto-run ACK0, auto-run ACK1 and Normal run modes.
V . CONCLUS ION
To increase the length of a data word beyond eight bits, multiplex the data into an
Am7968 TAXI Transmitter. This method uses less power, less board space, and lowers
the parts cost of the system.
