HA456 Data Sheet August 1999 120MHz, Low Power, 8 x 8 Video Crosspoint Switch File Number 4153.2 Features • Fully Buffered Inputs and Outputs (AV = +1) The HA456 is the first 8 x 8 video crosspoint switch suitable for high performance video systems. Its high level of integration significantly reduces component count, board space, and cost. The crosspoint switch contains a digitally controlled matrix of 64 fully buffered switches that connect eight video input signals to any, or all, matrix outputs. Each matrix output connects to an internal, high-speed (200V/µs), unity gain buffer capable of driving 400Ω and 5pF to ±2V. For applications requiring gain or increased drive capability, the HA456 outputs can be connected directly to two HFA1412 quad, gain of two video buffers, which are capable of driving 75Ω loads. This crosspoint’s true high impedance three-state output capability, makes it feasible to parallel multiple HA456s and form larger switch matrices. • Routes Any Input Channel to Any Output Channel • Switches Standard and High Resolution Video Signals • Serial or Parallel Digital Interface • Expandable for Larger Switch Matrices • Wide Bandwidth . . . . . . . . . . . . . . . . . . . . . . . . . . 120MHz • High Slew Rate. . . . . . . . . . . . . . . . . . . . . . . . . . . 200V/µs • Differential Gain and Phase . . . . . . . 0.05%, 0.05 Degrees • Low Crosstalk at 10MHz . . . . . . . . . . . . . . . . . . . . . -55dB Applications • Professional Video Switching and Routing • Security and Video Editing Systems Ordering Information TEMP.

Connect both DGND pins to AGND. 10 16 EDGE/LEVEL A user strapped input that defines whether synchronous channel switching is edge or level controlled. With this pin strapped high, the slave register loads from the master register (thus changing the switch matrix state) on the rising edge of the LATCH signal. If it is strapped low (level mode), the slave register is transparent while LATCH is low, passing data directly from the master register to the switch state decoders. Strapping EDGE/LEVEL and LATCH low causes the channel switch to execute on the WR rising edge (not recommended for serial mode operation). 12, 23, 38 18, 29, 44 V+ Positive Supply Voltage. Connect all V+ pins together and decouple each pin to AGND (Figure 2). 14 20 SER/PAR A user strapped input that defines whether the serial (SER/PAR=1) or parallel (SER/PAR=0) digital programming interface is being utilized. 16, 32 22, 38 V- Negative Supply Voltage. Connect both V- pins together and decouple each pin to AGND (Figure 2). 18 24 WR WRITE Input. In serial mode, data shifts into the shift register (Master Register) LSB from SER IN on the WR rising edge. In parallel mode, the Master Register loads with D3:0 (iff D3:0=0000 through 1000), or the appropriate action is taken (iff D3:0=1011 through 1111), on the WR rising edge (see Table 1). 19 25 LATCH Synchronous Channel Switch Control Input. If EDGE/LEVEL = 1, data is loaded from the Master Register to the Slave Register on the rising edge of LATCH. If EDGE/LEVEL = 0, data is loaded from the Master to the Slave Register while LATCH = 0. In parallel mode, commands 1011 through 1110 execute asynchronously, on the WR rising edge, regardless of the state of LATCH or EDGE/LEVEL. Parallel mode command 1111 executes a software “Latch” (see Table 1). 20 26 CE Chip Enable. When CE = 0 and CE = 1, the WR line is enabled. 21 27 CE Chip Enable.

Each input is fully buffered and presents a constant input capacitance whether the input connects to one output or all eight outputs. This yields consistent input termination impedances regardless of the switch configuration. The 8 matrix outputs are followed by 8 unity gain, wideband, tristatable buffers optimized for driving 400Ω and 5pF loads. The output disable function is useful for multiplexing two or more HA456s to create a larger input matrix (e.g., two multiplexed HA456s yield a 16x8 crosspoint). The HA456 outputs can be disabled individually or collectively under software control. When disabled, an output enters a high-impedance state. In multichip parallel applications, the disable function prevents inactive outputs from loading lines driven by other devices. Disabling an unused output also reduces power consumption. The HA456 outputs connect easily to two HFA1412 quad, gain-of-two buffers when 75Ω loads must be driven. Power-On RESET The HA456 has an internal power-on reset (POR) circuit that disables all outputs at power-up, and presets the switch matrix so that all outputs connect to IN0. In parallel mode, the desired switch state may be programmed before the outputs are enabled. In serial mode, all outputs are connected to GND each time they are enabled, so switch state programming must occur after the output is enabled. Digital Interface The desired switch state can be loaded using a 7-bit parallel interface mode or 32-bit serial interface mode (see Tables 1 through 3). All actions associated with the WR line occur on its rising edge. The same is true for the LATCH line if EDGE/LEVEL=1. Otherwise, the Slave Register updates asynchronously (while LATCH=0, if EDGE/LEVEL=0). WR is logically ANDed with CE and CE to allow active high or active low chip enable. 7-Bit Parallel Mode In the parallel programming mode (SER/PAR = 0), the 7 control bits (A2:0 and D3:0) typically specify an output channel (A2:0) and the corresponding action to be taken (D3:0). Command codes are available to enable or disable all outputs, or individual outputs, as shown in Table 1. Each output has 4-bit Master and Slave Registers associated with it, that hold the output’s currently selected input address (defined by D3:0). The input address - if applicable - is loaded into the Master Register on the rising edge of WR. If the HA456 is in level mode, and if LATCH=0 (asynchronous switching), then the input address flows through the transparent Slave Register, and the output immediately 6 switches to the new input. For synchronous switching on the rising edge of LATCH, strap the HA456 for edge mode, program all the desired switch connections, and then drive an inverted pulse on the LATCH input. Note: Operations defined by commands 1011 - 1111 occur asynchronously on the WR rising edge, without regard for the state of LATCH or EDGE/LEVEL. 32-Bit Serial Mode In the serial programming mode, all master registers are loaded with data, making it unnecessary to specify an output address (A2:0). The input data format is D3-D0, starting with OUT0 and ending with OUT7 for 32 total bits (i.e., first bit shifted in is D3 for OUT0, and 32nd bit shifted in is D0 for OUT7). Only codes 0000 through 1010 are valid serial mode commands. Code 1010 disables an individual output, while code 1001 enables it. After data is shifted into the 32-bit Master Register, it transfers to the Slave Register on the rising edge of the LATCH line (Edge mode), or when LATCH=0 (Level mode, see Figure 5).

These codes are for serial programming only. TABLE 2. SERIAL INTERFACE COMMANDS D3:0 0000 to 0111 ACTION Connect the output to the input channel defined by D3:0.

The default power-up state is all outputs disabled, so use this code to enable outputs after power is applied, but before programming the switch configuration. 1010 Disable the output. The output is no longer associated with any input channel; the desired input must be redefined after reenabling the output. 1011 to 1111 Do not use these codes in the serial programming mode.

This application shows the HA456 digital-switch control interface set up in the 7-bit parallel mode. The HA456 uses 7 data lines and 3 control lines (WR, CE and LATCH). The input/output information is presented to the chip at A2:0 and D3:0 by a parallel printer port. The data is stored in the Master Registers on the rising edge of WR. When the LATCH line goes high, the switch configuration loads into the Slave Registers, and all 8 outputs reconfigure at the same time. Each 7-bit word updates only one output at a time. If several outputs are to be updated, the data is individually loaded into the Master Registers. Then, a single LATCH pulse can reconfigure all channels simultaneously. An IBM compatible PC loads the programming data into the HA456 via its parallel port (LPT1) using a simple BASIC program. 8 HA456 HFA1412 (AV = +2) HA456 (MQFP PINOUT) 44 2 4 7 9 11 13 15 VIDEO INPUTS OUT0 IN0 IN1 IN2 IN3 IN4 IN5 IN6 IN7 OUT1 OUT2 OUT3 OUT4 OUT5 OUT6 OUT7 CE EDGE/LEVEL 1 2 3 4 5 19 18 V+ 41 40 36 34 1 43 42 D0/SER IN AGND D1/SER OUT DGND D2 VD3 A0 A1 SER/PAR A2 CE 19 LATCH 6 7 8 30 14 16 33 36 18 WR 37 RS 3 IN 1 35 33 31 29 26 24 22 21 10 RS 5 IN 2 10 IN 3 12 IN 4 75Ω OUT1 1 VOUT 7 OUT2 8 OUT3 14 OUT4 75Ω RS 12, 23, 38 25, 27, 30 5, 8 16, 32 V+ 4 -IN0:3 V11 2, 6 9, 13 -5V +5V -5V 14 20 NC NOTE: All decoupling capacitors 0.1µF Ceramic (1 per supply pin).
