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.

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 100Ωdifferential 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 video switching
• Datacom or telecom switching
