The TQ8034 is a non-blocking 34 X 34 digital crosspoint switch capable of data
rates greater than 1.6 Gigabits per second per port. Utilizing a fully differential
data path from input to output, the TQ8034 offers a high data rate with
exceptional fidelity. The symmetrical switching and noise rejection
characteristics inherent in differential logic result in low jitter, low crosstalk and
minimum signal skew. The TQ8034 is ideally suited for gigabit data and HDTV
switching applications.
The non-blocking architecture uses 34 fully independent 34:1 multiplexers,
allowing each output port to be independently programmed to any input port.
The TQ8034 supports full broadcast and multicast operation, with
programming modes optimized for these applications.
Four methods are provided for configuration of the switch. Two modes are
used for programming one input to one output at a time and the other two are
for programming one input to multiple outputs (1 to 34) at once. In all modes,
data integrity is maintained on all unchanged data paths.
