The TQ8032 is a non-blocking 32 x 32 digital crosspoint switch capable of
800 Megabits per second per port data rates. Utilizing a fully differential
internal data path and ECL I/O, the TQ8032 offers a high data rate with
exceptional signal fidelity. The symmetrical switching and noise rejection
characteristics inherent in differential logic result in low jitter and signal
skew. The TQ8032 is ideally suited for digital video, data communications
and telecommunication switching applications.
The non-blocking architecture uses 32 fully independent 32:1 multiplexers
(see diagram on page 2), allowing each output port to be independently
programmed to any input port. The switch is configured by sequentially
loading each multiplexer’s 5-bit program latch (OA0:4) with the desired
input port address (IA0:4) and enabling the LOAD pin. When complete, the
CONFIGURE pin is strobed and all new configurations are simultaneously
transferred into the switch multiplexers. Data integrity is maintained on all
unchanged data paths.
