The LMH6572 provides a 290-MHz bandwidth at 2-VPP output signal levels. The 140 MHz of 0.1-dB bandwidth and a 1500-V/µs slew rate make this part suitable for high definition television (HDTV) and high resolution multimedia video applications. The LMH6572 supports composite video applications with its 0.02% and 0.02° differential gain and phase errors for NTSC and PAL video signals while driving a single, back terminated 75-Ω load. The LM6572 can deliver 80-mA linear output current for driving multiple video load applications. The LMH6572 has an internal gain of 2 V/V (+6 dBv) for driving back terminated transmission lines at a net gain of 1 V/V (0 dBv). The LMH6572 is available in the SSOP package.

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 backterminated 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.

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%. 12 Submit Documentation Feedback Copyright © 2005–2018, Texas Instruments Incorporated Product Folder Links: LMH6572 LMH6572 www.ti.com SNCS102G – JUNE 2005 – REVISED AUGUST 2018 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.

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. Figure 23. Decoupling Capacitive Loads Figure 24. Recommended ROUT vs Capacitive Load 14 Figure 25.

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 (2) 3. Calculate the total RMS power: PT = PAMP + PD (3) 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 (4) 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.

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.
