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.
• Improved Replacement for GB4600
For applications requiring a tally output (enable indicator),
please refer to the HA4201 data sheet.

Application Information
General
510Ω
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-to-
output 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 75Ω resistor.

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!
Frequency Response
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.
Most applications utilizing the HA4600 require a series
output resistor, R , to tune the response for the specific load

Keep input and output traces as short as possible, because
trace inductance and capacitance can easily become the
performance limiting items.

table), so give careful consideration to component
placement to minimize trace length. As an example, -3dB

frequency response is obtained by cascading two levels of
crosspoints in the case of multiplexed outputs (see Figure 2),
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.
or distributing the load between two drivers if C is due to
L
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
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.
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.
