The circuit features very low power dissipation (105mW Enabled, 1mW Disabled), excellent differential gain and phase, and very high off isolation. When disabled, the output is switched to a high impedance state, making the HA4201 ideal for routing matrix equipment. The HA4201 requires no external current source, and features fast switching and symmetric slew rates. The tally output is an open collector PNP transistor to VCC , and is activated whenever EN = 1 to provide an indication of crosspoint selection.

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 (10F) tantalum in parallel with a small value (0.1F) chip capacitor works well in most cases. Keep input and output traces as short as possible, because trace inductance and capacitance can easily become the performance limiting items. 3 The HA4201 is a 1x1 crosspoint switch that is ideal for the matrix element in small, high input-to-output isolation switchers and routers. It also excels as an input buffer for routers with a large number of outputs (i.e. each input must connect to a large number of outputs) and delivers performance superior to most video amplifiers at a fraction of the cost. As an input buffer, the HA4201’s low input capacitance and high input resistance provide excellent video terminations when used with an external 75resistor. This crosspoint contains no feedback or gain setting resistors, so the output is a true high impedance load when the IC is disabled (EN = 0). Frequency Response Most applications utilizing the HA4201 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 on page 2), so give careful consideration to component placement to minimize trace length. As an example, -3dB bandwidth decreases to 160MHz for CL = 100pF, RS = 0. 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. FN3680.6 March 8, 2007 HA4201 matrix, and the HFA1112 (programmable gain buffer) as the gain of two output driver. Figure 2 details a 16x1 switcher (basically a 16:1 mux) which uses the HA4201 in a cascaded stage configuration to minimize capacitive loading at each output node, thus increasing system bandwidth. Control Signals EN - The ENABLE input is a TTL/CMOS compatible, active high input. When driven low this input forces the output to a true high impedance state and reduces the power dissipation by two orders of magnitude. The EN input has no on-chip pull-up resistor, so it must be connected to a logic high (recommend V+) if the enable function isn’t utilized. 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. Tally - The Tally output is an open collector PNP transistor connected to V+. When EN = 1, the PNP transistor is enabled and current is delivered to the load. When the crosspoint is disabled, the Tally output presents a very high impedance to the external circuitry. Several Tally outputs may be wire OR’d together to generate complex control signals, as shown with the HA4404 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.). Intersil’s Crosspoint Family Intersil offers a variety of 1x1 and 4x1 crosspoint switches. In addition to the HA4201, the 1x1 family includes the HA4600 which is an essentially similar device but without the Tally output. The 4x1 family is comprised of the HA4314, HA4404, and HA4344. The HA4314 is a 14 lead basic 4x1 crosspoint. The HA4404 is a 16 Ld device with Tally outputs to indicate the selected channel. The HA4344 is a 16 Ld 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. Switcher/Router Applications Figure 1 illustrates one possible implementation of a wideband, low-power, 4x4 switcher/router. A 4x4 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 HA4201 for the input buffer, the HA4404 (4x1 crosspoint switch) as the switch INPUT BUFFERS EN SOURCE0 75 OUT HA4201 SWITCH MATRIX RS IN0 IN0 T0 75 RS 75 IN3 IN3 T0 CS HA4404 OUT RS T3 IN0 HA4404 OUT OUT T0 CS HA4404 HA4404 SOURCE2 IN0 CS CS SOURCE1 T0 10k OUT RS T3 IN3 RS T3 IN3 T3 EN SOURCE3 75 OUT HA4201 10k RS OUTPUT BUFFERS (HFA1112 OR HFA1115) X2 + - 75 OUT0 X2 + - 75 OUT1 X2 + - 75 OUT2 X2 + - 75 OUT3 FIGURE 1. 4x4 SWITCHER/ROUTER APPLICATION 4 FN3680.6 March 8, 2007 HA4201 SWITCHING MATRIX SOURCE0 ISOLATION MUX OUTPUT BUFFER IN0 75 IN1 IN2 T0 IN3 SOURCE3 10k 75 T3 OUT IN0 OUT 75 IN1 T0 SOURCE4 IN2 EN RS RS HA4201 T3 IN3 SOURCE7 RS HFA1112 OR HFA1115 75 + HA4404 75 OUT X2 IN0 SOURCE8 75 IN1 IN2 SOURCE11 T0 IN3 75 T3 10k RS OUT IN0 OUT 75 IN1 T0 SOURCE12 IN2 RS EN RS HA4201 T3 IN3 SOURCE15 75 HA4404 FIGURE 2. 16x1 SWITCHER APPLICATION 5 FN3680.6 March 8, 2007 HA4201 VSUPPLY = 5V, TA = 25°C, RL = 10k, Unless Otherwise Specified 1.0 1.25 0.75 1.20 INPUT CAPACITANCE (pF) OUTPUT VOLTAGE (V) Typical Performance Curves 0.5 0.25 0 -0.25 -0.5 1.15 1.10 1.05 1.0 0.95 0.90 0.85 -0.75 0.80 -1.0 0.75 1 TIME (5ns/DIV.)
