3 ac test circuit 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 (10 f) tantalum in parallel with a small value (0.1 f) chip capacitor works well in most cases. keep input and output traces as short as possible, because trace inductance and capaci tance can easily become the performance limiting items. application information general the HA4201 is a 1 x 1 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 buffe r, the HA4201?s low input capacitance and high input re sistance provide excellent video terminations when used with an external 75 ? resistor. 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, r s , to tune the response for the specific load capacitance, c l , driven. bandwidth and slew rate degrade as c l increases (as shown in the electrical specification table), so give careful consideration to component placement to minimize trace l ength. as an example, -3db bandwidth decreases to 160mhz for c l = 100pf, r s = 0 ? . in big matrix configurations where c l 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 c l is due to bussing and subsequent stage input capacitance. 0.1db flat bandwidth r s = 82 ? , c l = 10pf 25 - 250 - mhz r s = 43 ? , c l = 15pf 25 - 175 - mhz r s = 36 ? , c l = 21pf 25 - 170 - mhz input resistance full 200 400 - k ? input capacitance full - 1.0 - pf enabled output resistance full - 15 - ? disabled output capacitance v en = 0.8v full - 2.0 - pf differential gain 4.43mhz, note 3 25 - 0.01 0.02 % differential phase 4.43mhz, note 3 25 - 0.01 0.02 degrees off isolation 1v p-p , 100mhz, v en = 0.8v, r l = 10 ? full - 85 - db slew rate (1.5v p-p , +sr/-sr) r s = 82 ? , c l = 10pf 25 - 1750/1770 - v/ s r s = 43 ? , c l = 15pf 25 - 1460/1360 - v/ s r s = 36 ? , c l = 21pf 25 - 1410/1360 - v/ s total harmonic distortion (note 3) full - 0.01 0.1 % disabled output resistance full - 12 - m ? note: 3. this parameter is not tested. the limits are guaranteed based on lab characterization, and reflect lot-to-lot variation. electrical specifications v supply = 5v, r l = 10kw, v en = 2.0v, unless otherwise specified (continued) parameter test conditions temp.

4 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. 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 t he load. when the crosspoint is disabled, the tally output presen ts a very high impedance to the external circuitry. severa l tally outputs may be wire or?d together to generate complex cont rol 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.). switcher/router applications figure 1 illustrates one possible implementation of a wideband, low power, 4 x 4 switcher/router. 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 HA4201 for the input buffer, the ha4404 (4 x 1 crosspoint switch) as the switch matrix, and the hfa1112 (programmable gain buffer) as the gain of two output driv er. figure 2 details a 16 x 1 switcher (basically a 16:1 mu x) which uses the HA4201 in a cascaded stage configuration to minimize capacitive loading at each output node, thus increasing system bandwidth. 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. intersil?s crosspoint family intersil offers a variety of 1 x 1 and 4 x 1 crosspoint switches. in addition to the HA4201, the 1 x 1 family includes the ha4600 which is an essentially similar device but without the tally output. the 4 x 1 family is comprised of the ha4314, ha4404, and ha4344. the ha4314 is a 14 lead basic 4 x 1 crosspoint. the ha4404 is a 16 lead device with tally outputs to indicate the selected channel. the ha4344 is a 16 lead crosspoint with synchroni zed 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. - input buffers switch matrix output buffers (hfa1112 or hfa1115) out source3 in0 t0 ha4404 cs t3 in3 en out0 10k ? 75 ? r s HA4201 out in0 t0 ha4404 cs t3 in3 out in0 t0 ha4404 cs t3 in3 out in0 t0 ha4404 cs t3 in3 75 ? out1 75 ? r s r s r s r s x2 + out source0 en 75 ? r s HA4201 out source1 75 ? source2 75 ? out2 75 ? out3 75 ? 10k ? x2 x2 x2 - + - + - + figure 1. 4 x 4 switcher/router application HA4201
