FMS6346 Six Channel, 6th Order SD/HD Video Filter Driver Features Description ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ The FMS6346 Low Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Six 6th order Butterworth filters provide improved image quality compared to typical passive solutions. The combination of low power Standard Definition (SD) and High Definition (HD) filters greatly simplify DVD video output circuitry. Three channels offer fixed SD filters while the other three are selectable between SD and HD filters. Three selectable sixth-order 8/32MHz (SD/HD) filters Three fixed sixth-order 8MHz (SD) filters Transparent input clamping Single video load drive (2Vpp, 150Ω, AV = 6dB) AC or DC-coupled inputs AC or DC-coupled outputs DC-coupled outputs eliminate AC-coupling capacitors Low power 5V only Robust (12kV HBM) output ESD protection Lead (Pb) free packages - TSSOP-20 The FMS6346 offers a fixed gain of 6dB. A metal option is available that provides a fixed gain of 9dB, offering even more flexibility. The FMS6346 may be directly driven by a DC-coupled DAC output or an AC-coupled signal. Internal diode clamps and bias circuitry may be used if AC-coupled inputs are required (see applications section for details). Applications ■ ■ ■ ■ ■ The outputs can drive AC or DC-coupled single (150Ω) video loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels will be offset approximately +280mV at the output.

In addition, the input will be slightly offset to optimize the output driver performance. The offset is held to the minimum required value to decrease the standing DC current into the load. Typical voltage levels are shown in the diagram below. YIN Driver YOUT 800kΩ 1.0 -> 1.02V Figure 10. Input Clamp Circuit 0.65 -> 0.67V I/O Configurations 0.3 -> 0.32V 0.0 -> 0.02V 2.28V 1.58V 0.88V 0.28V For DC-coupled DAC drive with DC-coupled outputs, use this configuration: VIN VOUT Driven by: DC-Coupled DAC Outputs AC-Coupled and Clamped Y, CV, R, G, B 0V - 1.4V DVD or STB SoC DAC Output LCVF Clamp Inactive 75Ω There will be a 280mV offset from the DC input level to the DC output level. VOUT = 2 * VIN + 280mV Figure 11. DC-coupled Inputs and Outputs 0.85V Alternatively, if the DAC’s average DC output level causes the signal to exceed the range of 0V to 1.4V, it can be AC-coupled as follows: 0.5V 0.15V VIN 0V - 1.4V 1.98V DVD or STB SoC DAC Output Driven by: AC-Coupled and Biased U, V, Pb, Pr, C 1.28V 0.58V VOUT 0.1u LCVF Clamp Active 75Ω Figure 9. Typical Voltage Levels The FMS6346 provides an internal diode clamp to support ACcoupled input signals. If the input signal does not go below ground, the input clamp will not operate. This allows DAC outputs to directly drive the FMS6346 without an AC coupling capacitor. The worst-case sync tip compression due to the clamp will not exceed 7mV. The input level set by the clamp combined with the internal DC offset will keep the output within its acceptable range. When the input is AC-coupled, the diode clamp will set the sync tip (or lowest voltage) just below ground. Figure 12. AC-coupled Inputs, DC-coupled Outputs When the FMS6346 is driven by an unknown external source or a SCART switch with its own clamping circuitry, the inputs should be AC-coupled as follows: 0V - 1.4V 0.1u External Video source must be AC-coupled. For symmetric signals like C, U, V, Cb, Cr, Pb and Pr, the average DC bias is fairly constant and the inputs can be AC-coupled with the addition of a pull-up resistor to set the DC input voltage. DAC outputs can also drive these same signals without the AC coupling capacitor. A conceptual illustration of the input clamp circuit is shown below: LCVF Clamp Active 75Ω 75Ω Figure 13. SCART Configuration with DC-coupled Outputs www.fairchildsemi.com 6 FMS6346 Rev. 1B The FMS6346 output drive configuration must be considered when calculating overall power dissipation. Care must be taken not to exceed the maximum die junction temperature. The following example can be used to calculate the FMS6346’s power dissipation and internal temperature rise.

Biased SCART with DC-coupled Outputs Vs = 5V The same circuits can be used with AC-coupled outputs if desired. RL = channel load resistance 0V - 1.4V DVD or STB SoC DAC Output LCVF Clamp Inactive Board layout can also affect thermal characteristics. Refer to the Layout Considerations Section for more information. 220u 75Ω Layout Considerations General layout and supply bypassing play major roles in high frequency performance and thermal characteristics. Fairchild offers a demonstration board, FMS6346DEMO, to use as a guide for layout and to aid in device testing and characterization. The FMS6346DEMO is a 4-layer board with a full power and ground plane. Following this layout configuration will provide the optimum performance and thermal characteristics. For optimum results, follow the steps below as a basis for high frequency layout: Figure 15. DC-coupled Inputs, AC-coupled Outputs 0V - 1.4V DVD or STB SoC DAC Output 0.1u LCVF Clamp Active 75Ω • Include 10µF and 0.1µF ceramic bypass capacitors 220μ • Place the 10µF capacitor within 0.75 inches of the power pin • Place the 0.1µF capacitor within 0.1 inches of the power pin • For multi-layer boards, use a large ground plane to help dissipate heat • For 2 layer boards, use a ground plane that extends beyond the device by at least 0.5” Figure 16. AC-coupled Inputs, AC-coupled Outputs • Minimize all trace lengths to reduce series inductances External video source must 7.5MΩ be AC-coupled. 0.1μ 75Ω LCVF Clamp Active 75Ω 220μ 500mV +/-350mV Figure 17. Biased SCART with AC-coupled Outputs NOTE: The video tilt or line time distortion will be dominated by the AC-coupling capacitor. The value may need to be increased beyond 220µF in order to obtain satisfactory operation in some applications. FMS6346 Rev. 1B 7 www.fairchildsemi.com FMS6346 Six Channel, 6th Order SD/HD Video Filter Driver Power Dissipation The same method can be used for biased signals with the addition of a pull-up resistor to make sure the clamp never operates. The internal pull-down resistance is 800kΩ ±20% so the external resistance should be 7.5MΩ to set the DC level to 500mV. If a pull-up resistance less than 7.5MΩ is desired, an external pull-down can be added such that the DC input level is set to 500mV.
