CONTROL
The TQ8004 is a non-blocking 4 X 4 digital crosspoint switch capable of
data rates greater than 2.7 Gigabits per second per port. Utilizing a fully
differential data path from input to output, the TQ8004 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 TQ8004 is ideal for high speed
data switching applications, as well as high fidelity buffering or protection
switching.
The non-blocking architecture uses 4 fully independent 4:1 multiplexers,
allowing each input port to be independently programmed to any output
port.
