AC Test Circuit PC Board Layout 500Ω 400Ω HA4404B 75Ω - RS VIN The frequency response of this circuit depends greatly on the care taken in designing the PC board. The use of low inductance components such as chip resistors and chip capacitors is strongly recommended, while a solid ground plane is a must! 510Ω VOUT + HFA1100 75Ω Attention should be given to decoupling the power supplies. A large value (10µF) tantalum in parallel with a small value (0.1µF) chip capacitor works well in most cases. 10kΩ CX NOTE: Keep input and output traces as short as possible, because trace inductance and capacitance can easily become the performance limiting items. CL = CX + Test Fixture Capacitance. 7 HA4404B Application Information T0-T3 - The Tally outputs are open collector PNP transistors connected to V+. When CS = 0, the PNP transistor associated with the selected input is enabled and current is delivered to the load. When the crosspoint is disabled, or the channel is unselected, the Tally output(s) present a very high impedance to the external circuitry. Several Tally outputs may be wire OR’d together to generate complex control signals, as shown in the application circuits below. The Tally load may be terminated to GND or to V- as long as the continuous output current doesn’t exceed 3mA (6mA at 50% duty cycle, etc.). General The HA4404B is a 4 x 1 crosspoint switch that is ideal for the matrix element of high performance switchers and routers. This crosspoint’s low input capacitance and high input resistance provide excellent video terminations when used with an external 75Ω resistor. Nevertheless, if several HA4404B inputs are connected together, the use of an input buffer should be considered (see Figure 1). This crosspoint contains no feedback or gain setting resistors, so the output is a true high impedance load when the IC is disabled (CS = 1). Ground Connections Switcher/Router Applications All GND pins are connected to a common point on the die, so any one of them will suffice as the functional GND connection. For the best isolation and crosstalk rejection, however, all GND pins must connect to the GND plane. Figure 1 illustrates one possible implementation of a wideband, low power, 4 x 4 switcher/router utilizing the HA4404B for the switch matrix. A 4 x 4 switcher/router allows any of the four outputs to be driven by any one of the four inputs (e.g., each of the four inputs may connect to a different output, or an input may connect to multiple outputs). This application utilizes the HA4600 (video buffer with output disable) for the input buffer, the HA4404B as the switch matrix, and the HFA1112 (programmable gain buffer) as the gain of two output driver. Figure 2 details a 16 x 1 switcher (basically a 16:1 mux) which uses the HA4201 (1 x 1 crosspoint) and the HA4404B in a cascaded stage configuration to minimize capacitive loading at each output node, thus increasing system bandwidth. Frequency Response Most applications utilizing the HA4404B require a series output resistor, RS, to tune the response for the specific load capacitance, CL, driven. Bandwidth and slew rate degrade as CL increases (as shown in the Electrical Specification table), so give careful consideration to component placement to minimize trace length. In big matrix configurations where CL is large, better frequency response is obtained by cascading two levels of crosspoints in the case of multiplexed outputs (see Figure 2), or distributing the load between two drivers if CL is due to bussing and subsequent stage input capacitance. Power Up Considerations No signals should be applied to the analog or digital inputs before the power supplies are activated. Latch-up may occur if the inputs are driven at the time of power up. To prevent latch-up, the input currents during power up must not exceed the values listed in the Absolute Maximum Ratings. Control Signals CS - This is a TTL/CMOS compatible, active low Chip Select input. When driven high, CS forces the output to a true high impedance state and reduces the power dissipation by a factor of 25. The CS input has no on-chip pull-down resistor, so it must be connected to a logic low (recommend GND) if the enable function isn’t utilized. Intersil’s Crosspoint Family Intersil offers a variety of 4 x 1 and 1 x 1 crosspoint switches. In addition to the HA4404B, the 4 x 1 family includes the HA4314 and HA4344. The HA4314 is a basic 14 lead device without Tally outputs. The HA4344 is a 16 lead crosspoint with synchronized control lines (A0, A1, CS). With synchronization, the control information for the next channel switch can be loaded into the crosspoint without affecting the current state. On a subsequent clock edge the stored control state effects the desired channel switch. A0, A1 - These are binary coded, TTL/CMOS compatible address inputs that select which one of the four inputs connect to the crosspoint output. The 1 x 1 family is comprised of the HA4201 and HA4600. They are essentially similar devices, but the HA4201 includes a Tally output. The 1 x 1s are useful as high performance video input buffers, or in a switch matrix requiring very high off isolation. 8 HA4404B SWITCH MATRIX INPUT BUFFERS 10kΩ EN SOURCE 0 75Ω OUT HA4600 RS IN0 T0 IN0 IN0 T0 T0 IN0 T0 HA4404B HA4404B HA4404B HA4404B CS CS CS CS SOURCE 1 75Ω RS RS OUT SOURCE 2 T3 IN3 RS OUT IN3 RS OUT IN3 T3 T3 OUT IN3 T3 75Ω EN SOURCE 3 75Ω OUT HA4600 10kΩ RS +- OUTPUT BUFFERS + X2 (HFA1112 OR HFA1115) 75Ω OUT0 +- +- X2 X2 X2 75Ω 75Ω 75Ω OUT1 OUT2 OUT3 FIGURE 1. 4 X 4 SWITCHER/ROUTER APPLICATION SWITCHING MATRIX HA4404B ISOLATION MUX OUTPUT BUFFER IN0 SOURCE0 75Ω IN1 IN2 IN3 SOURCE3 T0 10kΩ 75Ω T3 RS OUT IN0 OUT 75Ω IN1 T0 SOURCE4 EN RS RS HA4201 IN2 T3 IN3 SOURCE7 HFA1112 OR HFA1115 75Ω 75Ω - X2 IN0 SOURCE8 75Ω IN1 IN2 SOURCE11 IN3 75Ω T0 10kΩ T3 RS EN OUT IN0 OUT 75Ω IN1 T0 SOURCE12 IN2 SOURCE15 OUT + HA4404B RS HA4201 RS T3 IN3 75Ω HA4404B FIGURE 2. 16 X 1 SWITCHER APPLICATION 9 HA4404B Typical Performance Curves VSUPPLY = ±5V, TA = 25oC, RL = 10kΩ, Unless Otherwise Specified A1 (V) 1.0 1.6 0.25 0.8 0 -0.25 -0.5 -0.75 IN1 = +250mV IN3 = 0V A0 = +3V 2.4 0.5 OUTPUT VOLTAGE (mV) OUTPUT VOLTAGE (V) 0.75 0 250 125 0 -1.0 TIME (5ns/DIV.)
