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.

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. _______________________________________________________________________________________ 7 MAX4135/MAX4136 ______________________________________________________________Pin Description MAX4135/MAX4136 1-Input/6-Output Video Distribution Amplifiers 75Ω* +5VDC 0.1µF 75Ω* MAX4135 OUT1 1 OUT1 VCCO 2 OUT2 3 OUT2 SW1 SEL1 24 SW2 SEL2 23 SW3 SEL3 22 AGND 4 75Ω* -5VDC 0.1µF 75Ω* 75Ω* +5VDC 0.1µF 75Ω* OUT3 5 AGND 21 IN VIDEO IN 75Ω* VEEO 6 VEEO 7 OUT4 8 AGND 9 IN+ 20 OUT3 RF OUT4 OUT5 10 VCCO 11 OUT5 OUT6 12 OUT6 RG -5VDC VEEI 19 0.1µF AGND 18 N.C. 17 VCCI 16 0.1µF SW4 SEL4 15 SW5 SEL5 14 SW6 SEL6 13 +5VDC * TO TERMINATE TRANSMISSION LINE Figure 1. MAX4135 Typical Operating Circuit __________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. _______________________________________________________________________________________ 1-Input/6-Output Video Distribution Amplifiers +5VDC 0.1µF 75Ω* 75Ω* -5VDC 0.1µF 75Ω* 75Ω* +5VDC 0.1µF 75Ω* MAX4135/MAX4136 75Ω* MAX4136 OUT1 1 OUT1 VCCO 2 OUT2 3 OUT2 SW1 SEL1 24 SW2 SEL2 23 SW3 SEL3 22 AGND 4 AGND 21 OUT3 5 IN+ 20 OUT3 IN 75Ω* VEEO 6 VEEO 7 OUT4 8 AGND 9 VIDEO IN -5VDC VEEI 19 RG 18 OUT4 RF 17 VCCI 16 OUT5 10 VCCO 11 OUT5 OUT6 12 OUT6 SW4 SEL4 15 SW5 SEL5 14 SW6 SEL6 13 0.1µF RF RG +5VDC 0.1µF * TO TERMINATE TRANSMISSION LINE 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). _______________________________________________________________________________________ 9 14 12 CLOSED-LOOP GAIN (dB) RISO 10 CL = 15pF CL = 10pF CL = 5pF 8 VOUT VIN RL CL 6 4 2 MAX4135 MAX4136 0 0.1M 1M 10M 100M 1G 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. 10 Figure 4.

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. ______________________________________________________________________________________ 1-Input/6-Output Video Distribution Amplifiers MAX4135/MAX4136 SC1M3 SC1M2 SC1M1 SEL1 OUT1 OUT2 SEL2 CAMERA 1 SUBCARRIER (SC1) SEL3 OUT3 SEL4 OUT4 IN OUT5 75Ω SEL5 75Ω OUT6 VIDEO SEL6 SC1M6 SC1M5 SC1M4 MAX4135 MAX4136 SYNC 75Ω 75Ω MONITOR 1 75Ω VIDEO SC2M3 SC2M2 SC2M1 SYNC SEL1 75Ω 75Ω MONITOR 2 OUT2 SEL2 CAMERA 2 SUBCARRIER (SC2) 75Ω OUT1 SEL3 OUT3 SEL4 OUT4 IN VIDEO OUT5 75Ω SEL5 SYNC 75Ω 75Ω MONITOR 3 OUT6 MONITOR INPUTS SEL6 SC2M6 SC2M5 SC2M4 75Ω MAX4135 MAX4136 VIDEO 75Ω M3 M2 M1 MONITOR 4 VIDEO OUT1 75Ω OUT2 75Ω SYNC 75Ω OUT3 75Ω 75Ω MONITOR 5 SEL3 SEL4 OUT4 75Ω OUT5 75Ω OUT6 75Ω SEL2 IN 75Ω SEL5 SEL6 M6 M5 M4 75Ω 75Ω 75Ω SEL1 COMPOSITE SYNC (FROM GENLOCK) SYNC VIDEO SYNC 75Ω 75Ω MONITOR 6 MAX4135 MAX4136 Figure 6.
