www.fairchildsemi.com FMS6408 Features Triple Video Filter Driver for RGB and YUV Signals Description The FMS6408 provides three video signal paths including a two-input mux, a video filter and a 6dB gain output driver. The filter bandwidth supports RGB and YUV signals in either NTSC or PAL formats. The video filters approximate a 5th order Butterworth low pass characteristic optimized for minimum overshoot and flat group delay to provide excellent image quality. Four different peaking options are available. The video filters can be bypassed if desired. In a typical application, the RGB or YUV DAC outputs are AC coupled into the filters through the input mux. All channels have DC restore circuitry to clamp the DC input levels during video sync. The clamp pulse derived from the selected Y input controls three independent feedback clamps. All outputs are capable of driving 2Vpp, AC or DC coupled, into either a single (150Ω) or dual (75Ω) video load. The FMS6408 clamp levels can be factory programmed for YUV /RGB (250mV for all channels), YC / YPbPr (250mV on channel 1 and 1.125V on channels 2 and 3) or YC CV (250mV on channels 1 and 3 and 1.125V on channel 2). • 7.6MHz 5th order RGB/YUV/YC CV filters • 50dB stopband attenuation at 27MHz on all outputs • Better than 0.5dB flatness to 4.2MHz on all outputs • No external frequency selection components or clocks • AC coupled inputs and AC or DC coupled outputs • Supports both NTSC and PAL luminance bandwidth • Continuous time low pass filters for video anti-aliasing or reconstruction applications •

1. 物料型号: - 型号为FMS6408,由Fairchild Semiconductor生产。

2. 器件简介: - FMS6408是一款三通道视频滤波驱动器,用于RGB和YUV信号。它提供三个视频信号路径,包括双输入复用器、视频滤波器和6dB增益输出驱动器。该器件支持NTSC和PAL格式的RGB和YUV信号。

3. 引脚分配: - YINA(1):Y(亮度)或绿色输入A,必须连接包含同步信号的信号。 - UINA(2):U或蓝色输入A。 - VINA(3):V或红色输入A。 - GND(4):必须接地。 - YINB(5):Y(亮度)或绿色输入B,必须连接包含同步信号的信号。 - UINB(6):U或蓝色输入B。 - VINB(7):V或红色输入B。 - INMUX(A/B)(8):复用选择,A='1',B='0'。 - VOUT(9):V或红色输出。 - GND(10):必须接地。 - UOUT(11):U或蓝色输出。 - BYPASS(Bypass/Filter)(12):滤波器旁路,BYPASS='1',FILTER='0'。 - YOUT(13):Y或绿色输出。 - Vcc(14):+5V电源。

4. 参数特性: - 电源电流(Icc):52mA(典型值)。 - 输入电压最大值(V):1.4Vpp。 - 数字输入低电平(Vil):0.8V。 - 数字输入高电平(Vih):Vcc。 - 钳位电压(VCLAMP):YUV/RGB/CV输入250mV,PbPr/C输入1.125V。 - 电源抑制比(PSRR):-40dB。

5. 功能详解: - FMS6408设计用于从视频D/A源重建YUV、YC CV或RGB信号。输入应为AC耦合,而输出可以是AC或DC耦合。每个三个输出都能驱动2Vpp至75Ω负载。 - 所有通道在同步期间被钳位,以设置适当的DC输出电平。同步提示钳位大大减少了有效的输入时间常数,允许使用小型低成本输入耦合电容器。

6. 应用信息: - 应用于有线电视机顶盒、卫星机顶盒、地面机顶盒、DVD播放器、个人视频录像机(PVR)和视频点播(VOD)。

7. 封装信息: - 封装为MTC-14,具体尺寸和公差见PDF文档中的Package Dimensions部分。
