480MHz, 1x1 Video Crosspoint
Switch with Tally Output
FN3680.6
Features
• Low Power Dissipation . . . . . . . . . . . . . . . . . . . . . 105mW
The HA4201 is a very wide bandwidth 1x1 crosspoint switch
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 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.
For applications which don’t require a TALLY output, please
refer to the HA4600 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 (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 capacitance can easily become the
performance limiting items.

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 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, 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.

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
