Features - 16 PECL/CML fully differential (back-terminated) outputs - >2.5 Gb/s data bandwidth per channel - >40 Gb/s aggregate bandwidth SWITCHING PRODUCTS ADD15 +5V GND ADDØ 4-Bit Shift Register LOAD CLOCK ADDREN AUTOCONFIG Address Generator and Control RADDØ RADD1 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 munications, telemunication 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. - Non-blocking architecture - 80 ns configuration time - Autonomous control of external RAM for configuration data - Low jitter and signal skew - ±100 ps delay match (one input to all outputs) - Fully differential data path - 132-pin MLC package with heat spreader Applications - SONET OC-48 data path - Double-speed Fibre Channel - Hubs and routers - High-definition video switching -...
