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.
