TQ8025
2.5 Gigabit/sec
16x16 Digital
Crosspoint Switch
The TQ8025 is a non-blocking 16 x 16 digital crosspoint switch capable of
data rates greater than 2.5 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 port-
by-port and fast configuration options.
