HA4600
Data Sheet December 22, 2005 FN3990.8
480MHz, SOT-23, Video Buffer with Output Disable
The HA4600 is a very wide bandwidth, unity gain buffer ideal for professional video switching, HDTV, computer monitor routing, and other high performance applications. 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 HA4600 ideal for routing matrix equipment and video multiplexers. The HA4600 also features fast switching and symmetric slew rates. A typical application for the HA4600 is interfacing Intersil's wide range of video crosspoint switches. For applications requiring a tally output (enable indicator), please refer to the HA4201 data sheet.

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.

HA4600 Application Information
General
The HA4600 is a unity gain buffer that is optimized for high performance video applications. The output disable function makes it ideal for the matrix element in small, high input-tooutput isolation switchers and routers. This buffer contains no feedback or gain setting resistors, so the output is a true high impedance load when the IC is disabled (EN = 0). The HA4600 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 HA4600's low input capacitance and high input resistance provide excellent video terminations when used with an external 75 resistor. 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 HA4600, the 1 x 1 family includes the HA4201 which is an essentially similar device that includes a Tally output (enable indicator). 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 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.
Frequency Response
Most applications utilizing the HA4600 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. 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.
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.
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 HA4600 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 driver. Figure 2 details a 16 x 1 switcher (basically a 16:1 MUX) which uses the HA4600 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 4
