PC Board Layout 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! 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. The HA4314B 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 HA4314B 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 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. Frequency Response Most applications utilizing the HA4314B require a series output resistor, RS, to tune the response for the specific load 3 HA4314B 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 HA4314B in a cascaded stage configuration to minimize capacitive loading at each output node, thus increasing system bandwidth. 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 HA4314B, the 4 x 1 family includes the HA4404 and HA4344. The HA4404 is a 16 lead device with Tally outputs to indicate the selected channel. 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. Switcher/Router Applications Figure 1 illustrates one possible implementation of a wideband, low power, 4 x 4 switcher/router utilizing the HA4314B 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 HA4314B as the switch The 1 x 1 family is comprised of the HA4201 and HA4600. They are essentially similar devices, but the HA4201 includes a Tally output (enable indicator). The 1 x 1s are useful as high performance video input buffers, or in a switch matrix requiring very high off isolation.
