Shengbang Micro-electronics recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. ３ SGM9117 TYPICAL PERFORMANCE CHARACTERISTICS At VS = +5.0V, TA = +25℃, RL = 150Ω, all outputs AC coupled with 220µF, unless otherwise noted. 3 0 Frequency Response 270 180 Phase vs. Frequency Normalized Gain(dB) Phase(degree) -3 -6 -9 -12 -15 0.1 1 10 100 1000 90 0 -90 -180 -270 0.1 1 10 100 1000 Frequency(MHz) Frequency(MHz) Large Signal Step Response 0.8 0.3 0.2 Small Signal Step Response Output Voltage(V/) Output Voltage(V/) -0.025 0.025 0.075 0.4 0.1 0 -0.1 -0.2 0 -0.4 -0.8 -0.075 Time (µs) -0.3 -0.05 0 0.05 0.1 Time (µs) -50 -55 -60 -65 -70 -75 -80 -85 -90 -95 -100 0.01 PSRR vs. Frequency(Bypass Caps) 0 -10 -20 PSRR vs. Frequency(No Bypass Caps) PSRR(dB) PSRR(dB) -30 -40 -50 -60 -70 -80 0.01 0.1 1 10 100 0.1 1 10 100 Frequency(MHz) Frequency(MHz) ５ SGM9117 TYPICAL PERFORMANCE CHARACTERISTICS At VS = +5.0V, TA = +25℃, RL = 150Ω, all outputs AC coupled with 220µF, unless otherwise noted.

In application, SGM9117 is a fully integrated solution for buffering RGB or HDTV component signals in front of video decoder or behind video encoder. For example, SGM9117 can replace three amplifier drivers at R\G\B and Y\Pb\Pr output side in set-top box, Monitor and LCD TV, this solution can help you save PCB size and production cost, it also improves video signal performance comparing with traditional design using discrete components. SGM9117 features a DC-coupled input buffer, and a gain of +6dB in the output amplifier to drive 75Ω load. The AC or DC-coupled input buffer eliminates sync crush, droop, and field tilt. The output of SGM9117 also can be DC-coupled or AC-coupled. Typical Application Diagram The circuit in Figure 3 is normally used for AC coupled output and DC-coupled input with DAC which has an output voltage range of 0V to 1.4V. AC coupled output offers slightly lower power dissipation and high ESD protection ability. The schematics in Figure 1 and Figure 2 are also popular in design. +5V 0.1µF or 0.01µF 4 +VS R/Pr 75Ω 2 1 IN1 OUT1 8 75Ω R/Pr 10µF SGM9117 IN2 OUT2 7 75Ω G/Y G/Y Input Considerations Besides AC coupling, the SGM9117 inputs also can be DC-coupled. In DC coupling application, No input coupling capacitors are needed because the amplitude of input video signal from DAC includes ground and extends up to 1.4V, then SGM9117 can be directly connected to the output of a single-supply, current-output DAC without any external bias network. Some time, if DAC’s output level exceeds the range of 0V to 1.4V, or SGM9117 is driven by an unknown external source or a SCART switch which has its own clamping circuit, AC coupling is needed in such application.

While input is 0V, the SGM9117 output voltage is 260mV typically. In DC coupling design, one 75Ω resistor is used to Connect SGM9117’s output pin with external load directly, this serial back-termination resistor is used to match the impedance of the transmission line between SGM9117 and external load to cancel the signal reflection. The SGM9117 outputs can sink and source current allowing the device to be AC-coupled with external load, in AC coupling, 220µF at least capacitor will be used in order to cancel field tilt.

One 0.1µF and one 10µF capacitors are always used to Bypass VCC pin of SGM9117, please place these two capacitors as close to the SGM9117 output pin as possible, a large ground plane is also needed to ensure optimum performance. The input and output termination resistors should be placed as close to the related pin of SGM9117 as possible to avoid performance degradation. The PCB traces at the output side should have 75Ω characteristic impedance in order to match the 75Ω characteristic impedance cable connecting external load. In design, please keep the board trace at the inputs and outputs of the SGM9117 as short as possible to minimize the parasitic stray capacitance and noise pickup, designer needs to cavern out the ground layer under input and output trace in order to reduce stray capacitance and avoid signal peaking. ７ SGM9117 IN2 OUT2 7 75Ω 220µF G/Y G/Y 75Ω B/Pb 75Ω 3 IN3 OUT3 GND 5 6 75Ω 220µF B/Pb Figure 3.
