5 gigabits per second per port.
With a fully differential internal data path and PECL/CML I/O, the TQ8025 offers an extremely high data rate with exceptional signal fidelity.
The use of fully differential logic results in low crosstalk, jitter, and signal skew.
The TQ8025 is ideally suited for digital video, data communications, telecommunication switching, and cross-connect applications.
The non-blocking architecture uses 16 fully independent 16:1 multiplexers which allow each output port to be independently programmed to any input port.
The TQ8025 offers two programming options: a flexible port-by-port option, and a fast configuration option.
Using the fast configuration option, all 16 switch ports are programmed within 80ns by serially loading four 16-bit input port selection words.
Two output pins (RADD0,1) are provided to drive an external RAM (n x 4 x 16 bits) used to store the switch configuration.
An Autoconfigure option automatically transfers the new configurations into the switch core.
Autoconfiguration occurs after the last input selection word is clocked into the programming registers.
Data integrity is maintained on all unchanged data paths for both the portby-port and fast configuration options.
