GX9533

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 200ohm 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 impedance matching resistors. In applications where standard PECL levels are necessary, the GX9533 can be configured in "PECL Mode", to drive 800mV p-p into a 100ohm differential load. The power consumption in this mode increases to 860mW.
