MAX4135/MAX4136
_______________General Description
The MAX4135/MAX4136 are 1-input/6-output voltagefeedback amplifiers that combine high speed with fast
switching for video distribution applications. The
MAX4135 is internally set for a closed-loop gain of
2V/V, while the MAX4136 can be externally set for gains
of 2V/V or greater.
The MAX4135 achieves a -3dB bandwidth of 185MHz,
with 0.1dB gain flatness to 40MHz. The MAX4136’s
-3dB bandwidth is 140MHz. Both devices deliver a
1000V/µs slew rate, as well as exceptional full-power
bandwidths of 185MHz and 140MHz, respectively.
A 25ns channel switching time enables rapid multiplexing for picture-in-picture applications, yet maintains a
high off-isolation of 75dB and all-hostile crosstalk of
-50dB (f = 30MHz). The MAX4135/MAX4136’s on-board
logic selects any combination of the six signal outputs.
Each output is capable of swinging ±2V and delivering
65mA.
For applications that require a 1-input/4-output distribution amplifier, see the MAX4137/MAX4138 data sheet.

_______________Detailed Description
The MAX4135/MAX4136 are 1-input/6-output video distribution amplifiers. The MAX4135 is configured for a
fixed gain of +2, while the MAX4136 features external
gain control (feedback) for closed-loop gains of 2V/V or
greater.
Each output provides sufficient current to drive five
150Ω loads. However, distortion will increase when driving multiple loads. The TTL/CMOS-compatible digital
control (SEL_ ) enables or disables each output amplifier. When the SEL_ control input is low, the amplifier is
enabled; when it is high, the amplifier is disabled and
presents a high-impedance output. The enable/disable
or disable/enable time is under 25ns, which is useful in
multiplexing, pixel switching, or picture-in-picture applications.
Each device has an input amplifier, which buffers the
input from any switching glitches that may occur at the
output stage, and provides a high-impedance, lowcapacitance input. The separate input buffer allows a
true high output impedance when an amplifier is disabled.
The outputs are protected against short circuits to
ground. However, power-dissipation limits preclude
shorting all output channels to ground. See the PowerDissipation Considerations section for details.

__________Applications Information
Grounding, Bypassing,
and PC Board Layout
To obtain the MAX4135/MAX4136’s full 185MHz bandwidth, Microstrip and Stripline techniques are recommended in most cases. To ensure that the PC board
does not degrade the amplifier’s performance, design
the board for a frequency greater than 1GHz. Even with
very short traces, use these techniques at critical
points, such as inputs and outputs. Whether you use a
constant-impedance board or not, observe the following guidelines when designing the board:
8
• Do not use wire-wrap boards. They are too inductive.
• Do not use IC sockets. They increase parasitic
capacitance and inductance.
• In general, surface-mount components have shorter
leads and lower parasitic reactance, giving better
high-frequency performance than through-hole components.
• The PC board should have at least two layers, with
one side a signal layer and the other a ground plane.
• Keep signal lines as short and straight as possible.
Do not make 90° turns; round all corners.
• The ground plane should be as free from voids as
possible.

Figure 2. MAX4136 Typical Operating Circuit
Driving Capacitive Loads
The MAX4135/MAX4136 provide maximum AC performance with no output load capacitance. This is the
case when they are driving a correctly terminated transmission line (i.e., a back-terminated 75Ω cable).
However, the MAX4135/MAX4136 are capable of driving capacitive loads up to 10pF without oscillations,
but with reduced AC performance.
Driving large capacitive loads increases the chance of
oscillations in most amplifier circuits. This is especially
true for circuits with high loop gain, such as voltage followers. The amplifier’s output resistance and the load
capacitor combine to add a pole and excess phase to
the loop response. If the frequency of this pole is low
enough and phase margin is degraded sufficiently,
oscillations may occur.
A second problem when driving capacitive loads
results from the amplifier’s output impedance, which
looks inductive at high frequencies. This inductance
forms an L-C resonant circuit with the capacitive load,
which causes peaking in the frequency response and
degrades the amplifier’s gain margin.
The MAX4135/MAX4136 drive capacitive loads up to
10pF without oscillation. However, some peaking (in the
frequency domain) or ringing (in the time domain) may
occur (Figure 3).

FREQUENCY (Hz)
Figure 3. Effect of CLOAD on Frequency Response (without
RISO)
To drive larger-capacitance loads or to reduce ringing,
add an isolation resistor between the amplifier’s output
and the load, as shown in Figure 4.
The value of RISO depends on the circuit’s gain and the
capacitive load. Figure 5 shows the optimal isolation
resistor (RISO) vs. capacitive load (CL). At the higher
capacitor values, the bandwidth is dominated by the
RC network, formed by RISO and CL.
Power-Dissipation Considerations
The MAX4135/MAX4136 can drive up to six outputs
simultaneously. Quiescent power dissipation is typically
750mW and 800mW maximum, respectively, with all
channels enabled. The maximum package power dissipation is rated at 1540mW.
In a typical application, six outputs drive a standard
video signal into a 150Ω load. The amount of power
added to the quiescent dissipation is minimal and no
special precautions are necessary.
However, each output driving the maximum 65mA into
30Ω will cause a power-dissipation increase of approximately 200mW. Therefore, you should not allow more
than three outputs to deliver that load simultaneously.
Similarly, one output shorted to ground will cause a
power-dissipation increase of 650mW. Only one output
can be shorted to ground without violating the package
power rating.

Figure 5. Optimal Isolation Resistor (RISO) vs. CLOAD
In conclusion, during normal operation in a matchedload environment, the total power dissipation is well
within the package’s dissipation rating. The maximum
power dissipation is violated only if multiple channels
are driving the maximum current into minimum loads at
the same time.
