DESCRIPTION
DATA SHEET
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
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 100
differential load. The power consumption in this mode
increases to 860mW.
