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 wor ks 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. application information general the HA4314B is a 4 x 1 crosspoint switch that is ideal for the matrix element of high perfor mance switchers and routers. this crosspoint?s low input capacitance and high input resistance provide excellent video terminations when used with an external 75 ? 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. 0.1db flat bandwidth r s =50 ? , c l = 10pf 25 - 100 - mhz r s =20 ? , c l = 20pf 25 - 100 - mhz r s =16 ? , c l = 36pf 25 - 85 - mhz r s =13 ? , c l = 49pf 25 - 75 - mhz input resistance full 200 400 - k ? input capacitance full - 1.5 - pf enabled output resistance full - 15 - ? disabled output capacitance v cs = 2.0v full - 2.5 - 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 cs =2.0v, r l =10 ? full - 70 - db crosstalk rejection 1v p-p , 30mhz full - 80 - db slew rate (1.5v p-p , +sr/-sr) r s =50 ? , c l = 10pf 25 - 1425/1450 - v/ s r s =20 ? , c l = 20pf 25 - 1010/1010 - v/ s r s =16 ? , c l = 36pf 25 - 725/750 - v/ s r s =13 ? , c l = 49pf 25 - 600/650 - v/ s total harmonic distortion 10mhz, r l =1k ? , note 3 full - 0.01 0.1 % disabled output resistance v cs = 2.0v full - 12 - m ? notes: 3. this parameter is not tested. the limits are guaranteed based on lab characterization, and reflect lot-to-lot variation. 4. units are 100% tested at 25c; guaranteed but not tested at 0c and 70c. electrical specifications v supply = 5v, r l = 10k ? , v cs = 0.8v, unless otherwise specified (continued) parameter test conditions (note 4) temp.

4 frequency response most applications utilizing the HA4314B 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 trac e length. 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 (s ee figure 2), or distributing the load between two drivers if c l is due to bussing and subsequent stage input capacitance. 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. 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 s witcher/router utilizing the HA4314B for the switch matr ix. 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 ha 4600 (video buffer with output disable) for the input buffer, the HA4314B 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) whic h uses the ha4201 (1 x 1 crosspoint) and the HA4314B in a cascaded stage configuration to minimize capacitive loading at each output node, thus increasi ng 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 du ring power up must not exceed the values listed in the absolute maximum ratings. 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. 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. + - source 0 75 ? out source 1 source 2 source 3 75 ? 75 ? 75 ? ha4314 out cs in3 in0 ha4600 ha4600 en out en x2 r s r s 75 ? out0 r s ha4314 out cs in3 in0 x2 r s 75 ? out1 ha4314 out cs in3 in0 x2 r s 75 ? out2 ha4314 out cs in3 in0 x2 r s 75 ? out3 output buffers (hfa1112 or hfa1115) input buffers switch matrix +5v +5v + - + - + - figure 1. 4 x 4 switcher/router application HA4314B
