7 Detailed Description
7.1 Overview
The LMH6572 is a high-speed triple 2:1 analog multiplexer, optimized for very high speed and low distortion.
With a fixed gain of 2 and excellent AC performance, the LMH6572 is ideally suited for switching high resolution,
presentation grade video signals. The LMH6572 has no internal ground reference. Single or split supply
configurations are both possible. The LMH6572 features very high speed channel switching and disable times.
When disabled the LMH6572 output is high impedance, making multiplexer expansion possible by combining
multiple devices.
7.2 Feature Description
7.2.1 Single Supply Operation
The LMH6572 uses mid-supply referenced circuits for the select and disable pins. In order to use the LMH6572
in single supply configuration, it is necessary to use a circuit similar to Figure 19. In this configuration the logical
inputs are compatible with high breakdown open collector TTL, or open drain CMOS logic. In addition, the default
logic state is reversed since there is a pull-up resistor on those pins. Single supply operation also requires the
input to be biased to within the common mode input range of roughly ±2V from the mid-supply point.
7.2.2 Video Performance
The LMH6572 has been designed to provide excellent performance with production quality video signals in a
wide variety of formats such as HDTV and High Resolution VGA. Best performance will be obtained with back-
terminated loads. The back termination reduces reflections from the transmission line and effectively masks
transmission line and other parasitic capacitances from the amplifier output stage. Figure 18 shows a typical
configuration for driving a 75-Ω cable. The output buffer is configured for a gain of 2, so using back terminated
loads will give a net gain of 1.
Figure 18. Typical Application
Figure 19. Single Supply Application
7.2.3 Gain Accuracy
The gain accuracy of the LMH6572 is accurate to ±0.5% (0.3% typical) and stable over temperature. The internal
gain setting resistors, RF and RG, match very well; however, over process and temperature their absolute value
will change.

Feature Description (continued)
7.2.4 Expanding the Multiplexer
It is possible to build higher density multiplexers by paralleling several LMH6572s. Figure 20 shows a 4:1 RGB
MUX using two LMH6572s:
Figure 20. RGB MUX Using Two LMH6572's
If it is important in the end application to make sure that no two inputs are presented to the output at the same
time, an optional delay block can be added prior to the ENABLE(EN) pin of each device, as shown. Figure 21
shows one possible approach to this delay circuit. The delay circuit shown will delay ENABLE’s H to L transitions
(R1 and C1 decay) but will not delay its L to H transition.
Figure 21. Delay Circuit Implementation
R2 should be kept small compared to R1 in order to not reduce the ENABLE voltage and to produce little or no
delay to the ENABLE L to H transition.
With the ENABLE pin putting the output stage into a high impedance state, several LMH6572’s can be tied
together to form a larger input MUX. However, there is a slight loading effect on the active output caused by the
off-channel feedback and gain set resistors, as shown in Figure 21. Figure 22 is assuming there are four
LMH6572 devices tied together to form a triple 8:1 MUX. With the internal resistors valued at approximately
800Ω, the gain error is about -0.57 dB, or about −6%.

Feature Description (continued)
Figure 22. Multiplexer Input Expansion by Combining Outputs
An alternate approach would be to tie the outputs directly together and let all devices share a common back
termination resistor in order to alleviate the gain error issue above.
The drawback in this case is the increased capacitive load presented to the output of each LMH6572 due to the
offstate capacitance of the LMH6572.

Feature Description (continued)
7.2.5 Other Applications
The LMH6572 may be utilized in systems that involve a single RGB channel as well whenever there is a need to
switch between different “flavors” of a single RGB input.
Here are some examples:
1. RGB positive polarity, negative polarity switch
2. RGB full resolution, high-pass filter switch
In each of these applications, the same RGB input occupies one set of inputs to the LMH6572 and the other
“flavor” would be tied to the other input set.
7.2.5.1 Driving Capacitive Loads
Capacitive output loading applications will benefit from the use of a series output resistor. Figure 23 shows the
use of a series output resistor, ROUT, to stabilize the amplifier output under capacitive loading. Capacitive loads of
5 to 120 pF are the most critical, causing ringing, frequency response peaking and possible oscillation. Figure 24
gives a recommended value for selecting a series output resistor for mitigating capacitive loads. The values
suggested in the charts are selected for .5 dB or less of peaking in the frequency response. This gives a good
compromise between settling time and bandwidth. For applications where maximum frequency response is
needed and some peaking is tolerable, the value of ROUT can be reduced slightly from the recommended values.

8 Power Supply Recommendations
8.1 Power Dissipation
The LMH6572 is optimized for maximum speed and performance in the small form factor of the standard SSOP
package. To achieve its high level of performance, the LMH6572 consumes 23 mA of quiescent current, which
cannot be neglected when considering the total package power dissipation limit. To ensure maximum output
drive and highest performance, thermal shutdown is not provided. Therefore, it is of utmost importance to make
sure that the TJMAX is never exceeded due to the overall power dissipation.
Follow these steps to determine the Maximum power dissipation for the LMH6572:
1. Calculate the quiescent (no-load) power:
PAMP = ICC* (VS)
where
•
VS = V+ - V−
(1)
2. Calculate the RMS power dissipated in the output stage:
PD (rms) = rms [(VS - VOUT) * IOUT
]
where
•
•
VOUT and IOUT are the voltage across and the current through the external load
VS is the total supply voltage

3. Calculate the total RMS power:
PT = PAMP + PD
The maximum power that the LMH6572 package can dissipate at a given temperature can be derived with the
following equation:
PMAX = (150°C – TAMB)/ θJA
where
•
•
•
TAMB = Ambient temperature (°C)
θJA = Thermal resistance, from junction to ambient, for a given package (°C/W)
For the SSOP package θJA is 125 °C/W

8.2 ESD Protection
The LMH6572 is protected against electrostatic discharge (ESD) on all pins. The LMH6572 will survive 2000V
Human Body model and 200V Machine model events. Under normal operation the ESD diodes have no effect on
circuit performance. There are occasions, however, when the ESD diodes will be evident. If the LMH6572 is
driven by a large signal while the device is powered down the ESD diodes will conduct. The current that flows
through the ESD diodes will either exit the chip through the supply pins or will flow through the device, hence it is
possible to power up a chip with a large signal applied to the input pins. Shorting the power pins to each other
will prevent the chip from being powered up through the input.

9 Layout
9.1 Layout Guidelines
Whenever questions about layout arise, use the LMH730151 evaluation board as a guide. To reduce parasitic
capacitances, ground and power planes should be removed near the input and output pins. For long signal paths
controlled impedance lines should be used, along with impedance matching elements at both ends. Bypass
capacitors should be placed as close to the device as possible. Bypass capacitors from each rail to ground are
applied in pairs. The larger electrolytic bypass capacitors can be located farther from the device; however, the
smaller ceramic capacitors should be placed as close to the device as possible. In Figure 18 and Figure 19, the
capacitor between V+ and V− is optional, but is recommended for best second harmonic distortion. Another way
to enhance performance is to use pairs of 0.01 μF and 0.1 μF ceramic capacitors for each supply bypass.
9.1.1 Evaluation Boards
Texas Instruments provides the following evaluation boards as a guide for high frequency layout and as an aid in
device testing and characterization. Many of the datasheet plots were measured with these boards.
