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 200Ω

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 800mVp-p into a

100Ω differential load. The power consumption in this

mode increases to 860mW.

3. Detailed Description

3.1 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 3-1 or Figure 3-2.

Figure 3-1: Preferred Termination Of Unused Inputs

Figure 3-2: Alternate Termination of Unused Inputs

Terminating the inputs as shown in Figure 3-1 will provide the highest noise immunity,

since there is no possibility of noise coupling into the unconnected input pin.

3.2 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:

3.2.1 Stage One: Loading the Configuration Into Latches

1. The output address is selected on the OA pins as shown in Table 3-1.

2. The input address is selected on the IA pins as shown in Table 3-2.

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.

Proprietary & Confidential

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.

Note that a QUIET mode is available as shown in Table 3-2. In QUIET mode, the outputs

are latched in a DC state with OUTX = 1 and OUTX = 0.

3.2.2 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 3-4 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.

4. Using the GX9533 to Expand Larger Matrices

The GX9533 pin-out and architecture provides a number of advantages over other

crosspoint switches in the area of switching matrix board layout.

Figure 4-1: Crosspoint Matrix Expansion - 16x16 Crosspoint Matrix

4.1 Bus Through™ Pin Connections

To easily facilitate a switching matrix design where inputs can be bussed across a matrix

of crosspoint devices, Gennum's crosspoint device has "NC" pins opposite the input pins

as shown by the dotted lines in the pin-out diagram above. This design allows bussing of

inputs without having to use "vias" to get below the top layer of the printed circuit board.

4.2 Expansion Port Input

The expansion inputs provide the following benefits:

• by not having to run traces from the outputs of the crosspoint switch to a common

output bus, crosstalk between output channels can be greatly reduced.

• fewer circuit board layers are required because the outputs of each device simply

line up

• there are no transmission line effects caused by connecting High-Z outputs to an

output bus

• because the output signal is being routed from the top of the switching matrix to the

bottom through the devices, inputs can be simply bussed across the board without

having to worry about input/output crosstalk.
