GENLINX II GX9533 Serial Digital 8x9 Crosspoint DATA SHEET FEATURES operation beyond 622Mb/s accepts SMPTE and PECL input levels fully differential signal path on-chip PECL current loads eliminate need for external pull-down resistors capable of driving 100 differential loads very low 500mW power consumption additional expansion port input for construction of larger matrices auxiliary monitoring output easy to configure double latched address inputs with separate load and configure TTL/CMOS compatible control logic inputs single 5V power supply APPLICATIONS Serial digital switching. video switching; datacom or telecom DESCRIPTION The GX9533 is a high speed 8x9 serial digital crosspoint. An expansion input port eases the design of larger switching matrices by reducing PCB layers and eliminating the need for cascaded secondary switching. Decode logic and double level latching to configure the matrix are included on chip. Separate LOAD and CONFIGURE inputs allow for asynchronous configuration and synchronous switching. These latches can also be made transparent for asynchronous switching by pulling the LOAD and CONFIGURE pins high. In the power saving (PS) mode, the GX9533 has a very low power consumption of 500mW. This is accomplished by driving a 400mV output swing into the on-chip 200 differential load termination in the expansion port of the next GX9533. This architecture provides a significant power savings and the elimination of external load resistors or imped……
