1-Input/6-Output Video Distribution Amplifiers
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.

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.

_______________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).

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.
