It incorporates three high-definition (HD) filter channels. All filters feature sixth-order Butterworth characteristics that are useful as digital-to-analog converter (DAC) reconstruction filters or as analog-to-digital converter (ADC) anti-aliasing filters. The HD filters can be bypassed to support filters. The HD filters can be bypassed to support 1080p60 video or up to quad extended graphics array (QXGA) RGB video. As part of the TP133A flexibility, the input can be configured for ac- or dc-coupled inputs. The 84-mV output level shift allows for a full sync dynamic range at the output with 0-V input. The ac-coupled modes include a transparent sync-tip clamp option for Y', and G'B'R' signals. AC- coupled biasing for C'/P'B/P'R channels can easily be achieved by adding an external resistor to VS+. The TP133A rail-to-rail output stage with 6-dB gain allows for both ac and dc line driving. The ability to drive two lines, or 75-Ω loads, allows for maximum flexibility as a video line driver. The 27.6-mA total quiescent current at 3.3 V makes it an excellent choice for power-sensitive video applications. TPF133A is available in SOIC-8 package. Its operation temperature range is from −40°C to +85°C.

Reference Application Design REV1.1 www.3peakic.com ~5~ ©2011 3PEAK INCORPORATED TPF133A Low Power, 3-channel Video Filter for HD Video Application Information The TPF133A is targeted for systems that require three high-definition (HD) video outputs. Although it can be used for numerous other applications, the needs and requirements of the video signal are the most important design parameters of the TPF133A. The TPF133A incorporates many features not typically found in integrated video parts while consuming very low power. Internal Sync Clamp The typical embedded video DAC operates from a ground referenced single supply. This becomes an issue because the lower level of the sync pulse output may be at a 0V reference level to some positive level. The problem is presenting a 0V input to most single supply driven amplifiers will saturate the output stage of the amplifier resulting in a clipped sync tip and degrading the video image. A larger positive reference may offset the input above its positive range. The TPF133A features an internal sync clamp and offset function to level shift the entire video signal to the best level before it reaches the input of the amplifier stage. These features are also helpful to avoid saturation of the output stage of the amplifier by setting the signal closer to the best voltage range. The simplified block diagram of the TPF133A in Figure-2. The AC coupled video sync signal is pulled negative by a current source at the input of the comparator amplifier. When the sync tip goes below the comparator threshold the output comparator is driven negative, The PMOS device turns on clamping sync tip to near ground level. The network triggers on the sync tip of video signal. Droop Voltage and DC Restoration Selection of the input AC-coupling capacitance is based on the system requirements. A typical sync tip width of a 64μs NTSC line is 4μs during which clamp circuit restores its DC level. In the remaining 60μs period, the voltage droops because of a small constant 2.0μA sinking current. If the AC-coupling ©2011 3PEAK INCORPORATED capacitance is 0.1μF, the maximum droop voltage is about 1mV which is restored by the clamp circuit. The maximum pull-up current of the clamp circuit is 1.7mA. For a 4μs sync tip width and 0.1μF capacitor, the maximum restoration voltage is about 80mV. The line droop voltage will increase if a smaller AC-coupling capacitance is used. For the same reason, if larger capacitance is used the line droop voltage will decrease. Table 1 is droop voltage and maximum restoration voltage of the clamp for typical capacitance. Table 1.

This provides a very stable low pass function, and in the case of the TPF133A, the six-pole roll-off at around 36MHz. The six-pole function is accomplished with an RC low pass network placed in series with and before the Sallen Key. Output Couple TPF133A output could support both “AC Couple” and “DC Couple”, if use “AC Couple”, this capacitor is typically between 220-μF and 1000-μF, although 470-μF is common. This value of this capacitor must be this large to minimize the line tilt (droop) and/or field tilt associated with ac-coupling as described previously in this document. The TPF133A internal sync clamp makes it possible to DC couple the output to a video load, eliminating the need for any AC coupling capacitors, thereby saving board space and additional expense for capacitors. This makes the TPF133A extremely attractive for portable video applications. Additionally, this solution completely eliminates the issue of field tilt in the lower frequency. The trade off is greater demand of supply current. Typical load current for AC coupled is around 1mA, compared to typical 6.6mA used when DC ~ 6 ~ REV 1.1 www.3peakic.com TPF133A Low Power, 3-channel Video Filter for HD Video coupling. PDMAX =Vs  I SMAX +（Vs  VOUT） Output Drive Capability and Power Dissipation With the high output drive capability of the TPF133A, it is possible to exceed the +125°C absolute maximum junction temperature under certain load current conditions. Therefore, it is important to calculate the maximum junction temperature for an application to determine if load conditions or package types need to be modified to assure operation of the amplifier in a safe operating area. The maximum power dissipation allowed in a package is determined according to Equation: PDMAX = TJMAX  TAMAX  JA Where： TJMAX = Maximum junction temperature TAMAX = Maximum ambient temperature ΘJA = Thermal resistance of the package The maximum power dissipation actually produced by an IC is the total quiescent supply current times the total power supply voltage, plus the power in the IC due to the load, or: for sourcing: VOUT RL Where： VS = Supply voltage ISMAX = Maximum quiescent supply current VOUT = Maximum output voltage of the application RLOAD = Load resistance tied to ground By setting the two PDMAX equations equal to each other, we can solve the output current and RLOAD to avoid the device overheat. Power Supply Bypassing Printed Circuit Board Layout As with any modern operational amplifier, a good printed circuit board layout is necessary for optimum performance. Lead lengths should be as short as possible. The power supply pin must be well bypassed to reduce the risk of oscillation. For normal single supply operation, a single 4.7μF tantalum capacitor in parallel with a 0.1μF ceramic capacitor from VS+ to GND will suffice.   VIDEO FILTER DRIVER SELECTION GUIDE P/N Product Description Channel -3dB Bandwidth Package TPF110 /TPF110L Low power, enable function and 1-SD 9MHz SC70-5 SOT23-6 3-SD 9MHz SO-8 4-SD 9MHz MSOP-10 TSSOP-14 6-SD 9MHz TSSOP-14 3-ED 13.5MHz SO-8 3-HD 36MHz SO-8 1-SD& 3-SD 9MHz 36MHz MSOP-10 TSSOP-14 SAG correction, 1 channel 6th order 9MHz TPF113 Low power 3 channel, 6th-order 9MHz SD video filter TPF114 Low power 4 channel, 6th-order 9MHz SD video filter TPF116 Low power 4 channel, 6th-order 9MHz SD video filter for CVBS, SVIDEO TPF123 3 channel 6th-order 13.5MHz, 960H/720H-CVBS video filter or Y’Pb’Pr 480P/576P video filter TPF133 Low power 3 channel, 6th-order 36MHz HD video filter TPF134 Low power 3 channel, 6th-order 36MHz HD video filter and 1 channel SD video filter REV1.1 www.3peakic.com ~7~ ©2011 3PEAK INCORPORATED TPF133A Low Power, 3-channel Video Filter for HD Video TPF136 Low power 3 channel, 6th-order 36MHz HD video filter and 3 channel 3-SD& 3-HD 9MHz 36MHz TSSOP-20 3-FHD 72MHz SO-8 1-SD& 3-FHD 9MHz 72MHz MSOP-10 TSSOP-14 3-SD& 3-FHD 9MHz 72MHz TSSOP-20 3-CH 220MHz SO-8 SD video filter TPF143 Low power 3 channel, 6th-order 72MHz Full HD video filter TPF144 Low power 3 channel, 6th-order 72MHz Full HD video filter and 1 channel SD video filter TPF146 Low power 3 channel, 6th-order 72MHz Full HD video filter and3 channel SD video filter TPF153 Low power 3 channel, 6th-order 220MHz Full HD video filter ©2011 3PEAK INCORPORATED ~ 8 ~ REV 1.1 www.3peakic.com TPF133A Low Power, 3-channel Video Filter for HD Video Package Outline Dimensions SOIC-8 REV1.1 www.3peakic.com ~9~ Symbol Dimensions In Millimeters Min Max Dimensions In Inches Min Max A 1.350 1.750 0.053 0.069 A1 0.100 0.250 0.004 0.010 A2 1.350 1.550 0.053 0.061 B 0.330 0.510 0.013 0.020 C 0.190 0.250 0.007 0.010 D 4.780 5.000 0.188 0.197 E 3.800 4.000 0.150 0.157 E1 5.800 6.300 0.228 0.248 e 1.270TYP L1 0.400 1.270 0.016 0.050 θ 0° 8° 0° 8° 0.050TYP ©2011 3PEAK INCORPORATED TPF133A Low Power, 3-channel Video Filter for HD Video IMPORTANT NOTICE "PRELIMINARY" PRODUCT INFORMATION DESCRIBES PRODUCTS THAT ARE IN PRODUCTION, BUT FOR WHICH FULL CHARACTERIZATION DATA IS NOT YET AVAILABLE. 3PEAKIC MICROELECTRONICS CO.
