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.

DETAILED DESCRIPTION
DIFFERENTIAL INPUTS
The inputs to the GX9533 will accept both SMPTE 259M as
well as PECL input levels. The fully differential data path
provides low jitter data rates of up to 700Mb/s.
The main inputs (IN0..7) and expansion inputs (EXP0..7) are
normally connected to a biased differential data source.
The GX9533 inputs are not self biased, so unused inputs
should be connected as shown in Figure 3 or Figure 4.

Terminating the inputs as shown in Figure 3 will provide the
highest noise immunity, since there is no possibility of noise
coupling into the unconnected input pin.
I/O ADDRESS SELECTION
The GX9533 has a versatile LOAD/CONFIGURE
architecture which simplifies IN/OUT switch configuration.
An output is normally connected to an input by a two stage
process:
Stage One: Loading The Configuration Into Latches
1. The output address is selected on the OA pins as
shown in Table 1.
2. The input address is selected on the IA pins as shown in
Table 2.
3. A LOAD pulse then transfers the output and input
addresses into the GX9533 LOAD latch.
The above three steps can be repeated up to eight times in
order to configure the latch for all eight outputs.
During step 3 above, if the LOADA pulse is also strobed,
the latch is configured to connect the selected input to the
ninth, auxiliary output.

Mode
Note that a QUIET mode is available as shown in Table 2. In
QUIET mode, the outputs are latched in a DC state with
OUTX = 1 and OUTX = 0.
Stage Two: Configuring The Matrix
A CONFIGURE strobe is applied to transfer the contents of
the LOAD latch into the CONFIG latch. This action will
cause the data flow through the GX9533 to be switched to
the new configuration. Refer to Figure 6 for detailed timing
information.
Note that any single output can be asynchronously
switched by having LOAD (or LOADA if desired) held high
while CONFIG is strobed.
