GENLINX™ II GX9533 Serial Digital 8x9 Crosspoint Features Description • 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 100Ω differential loads • very low 500mW power consumption • additional expansion port input for construction of larger matrices 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. • 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 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.

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. VCC INx GX9533 INx 1k Figure 3-1: Preferred Termination Of Unused Inputs VCC INX GX9533 NC INX 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.

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. GX9533 Serial Digital 8x9 Crosspoint Data Sheet 8494 - 4 November 2009 10 of 15 Proprietary & Confidential 3.3 Output Level Select A single resistor, RSET, is used to set the amplitude of all differential outputs.

Using the GX9533 to Expand Larger Matrices INPUTS 0-7 INPUTS 8-15 The GX9533 pin-out and architecture provides a number of advantages over other crosspoint switches in the area of switching matrix board layout.

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.
