sgm9116 triple, 35mhz, 6th-order hdtv video filter driver product description the sgm9116 is a video buffer which integrates triple 6db gain rail-to-rail output drivers and triple 6th-oder output reconstruction filters with a -3db bandwidth of 35mhz and 159v/s slew rate. sgm9116 provides improved image quality compared with passive lc filters and discrete drivers solution. operating from single power supply ranging from 3.3v to 5.5v and sinking an ultra-low 39.4ma quiescent current, the sgm9116 is ideally suited for battery powered applications. sgm9116 can be dc-coupled or ac-coupled with input video signal, such as the output stage of dac to eliminate out-of-band noise. internal diode clamps and bias circuitry may be used if ac-coupled inputs are required. sgm9116 also integrates an internal level shift circuit which avoids sync-pulse being clipped and allows dc-coupled output. the drivers in sgm9116 can drive dc- or ac-coupled single (150 ? ) or dual (75 ? ) loads. the sgm9116 is available in green soic-8 package. features ? triple 6th-order 35mhz (hd) filters ? transparent input clamping ? 6db output driver gain and drive dual video loads ? rail-to-rail output ? input voltage range includes ground ? ac- or dc-coupled inputs ? ac- or dc-coupled outputs ? operates from 3.3v to 5.5v single power supply ? low power 39.4ma total supply current ? available in green soic-8 package applications video amplifiers cable and satellite set-top boxes communication devices video on demand portable and handheld products personal video recorders dvd players hdtv projectors block diagram 35mhz, 6th-order transparent clamp 6db in1 out1 35mhz, 6th-order transparent clamp 6db in3 out3 35mhz, 6th-order transparent clamp 6db in2 out2 rev. c. 3 sg micro corp www.sg-micro.com

triple, 35mhz, 6th-order hdtv video filter driver 6 sg micro corp www.sg-micro.com sgm9116 application information functional description sgm9116 operates from a single 3.3v to 5.5v supply. in application, sgm9116 is a fully integrated solution for filtering and buffering hdtv signals in front of video decoder or behind video encoder. for example, sgm9116 can replace three passive lc filters and three amplifier drivers at r\g\b and y\pb\pr output side in set-top box and dvd player. this solution can help reduce pcb size and production cost, and it also improves video signal performance comparing with traditional design using discrete components. sgm9116 features a dc-coupled input buffer, a 6th-order low-pass filter to eliminate out-of-band noise of video encoder, and a gain of 6db in the output amplifier to drive 75 ? load. the ac- or dc-coupled input buffer eliminates sync crush, droop, and field tilt. the output of sgm9116 also can be dc-coupled or ac-coupled. input considerations besides ac coupling, the sgm9116 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, and sgm9116 can be directly connected to the output of a single-supply, current-output dac without any external bias network. in applications where dac?s output level exceeds the range from 0v to 1.4v, or sgm9116 is driven by an unknown external source or a scart switch which has its own clamping circuit, ac coupling is needed. output considerations the sgm9116 outputs can be dc-coupled or ac-coupled. when input is 0v, the sgm9116 output voltage is 494mv typically. in dc coupling design, one 75 ? resistor is used to connect sgm9116?s output pin with external load directly, and this serial back-termination resistor is used to match the impedance of the transmission line between sgm9116 and external load to cancel the signal reflection. the sgm9116 outputs can sink and source current allowing the device to be ac-coupled with external load. in ac coupling, at least 220f capacitor will be used in order to eliminate field tilt. power-supply bypassing and layout correct power supply bypassing is very important for optimizing video performance in design. one 0.1f and one 10f capacitors are always used to bypass +v s pin of sgm9116. place these two capacitors as close to the sgm9116 supply 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 pins of sgm9116 as possible to avoid performance degradation. the pcb traces at the output side should have 75 ? characteristic impedance in order to match the 75 ? characteristic impedance of the cable connecting external load. in design, keep the board trace at the inputs and outputs of the sgm9116 as short as possible to minimize the parasitic stray capacitance and noise pickup.
