FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE Document Overview The Hardware Reference provides information needed to integrate the FS453 Video Processor into system hardware. The reference is divided into eight sections: 1. Introduction – explains the purpose and general flow of the FS453.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 1. Introduction 1.1 General Description The FS453 PC to TV Video Scan Converter provi des broadcast-quality scan conversion for graphics cards, motherboard chip sets, video game consoles, consumer electronics and other PC-to-TV applications.

FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE is used to achieve the finest clock resolution, using a dithered clock. In PLL mode, the NCO is bypassed and the clock is not dithered. The NCO can be used when HTOTAL and VTOTAL values have additional constraints that prevent sele ction of values that are factors of the TV pixel rate.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 3. Technical Highlights Creating clear, broadcast quality television video from high resolution computer graphics is a complex process. PC-to-TV Video Scan C onverters have to surmount many technical obstacles.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 3.2 Flicker Reduction Computer images are displayed progressively. That is, for a given frame of video, each line of video is scanned onto the monitor sequentially. SDTV images, how ever, are interlaced.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 3.3 Video Encoding Unlike component video formats (PC and HDTV) that process the color information separately to avoid interference, broadcast SDTV combi nes all picture information into a single, composite signal.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 4. Scaling and Positioning Notes The FS453 graphics converter does not use a frame me mory. Therefore, the FS453 input video frame rate must be synchronous to and match the output video field or frame rate.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 4.2 Horizontal Scaling While vertical scaling is linked to the VTOTAL rati o, horizontal scaling is arbitrary and not linked to HTOTAL at all. The horizontal scaler is simply programmed with the ratio desired between TV_HACTIVE and GCC_HACTIVE.

FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 9. Component Placement This section gives guidelines for the placement and layout of components a ssociated with the FS453. A printed circuit board (PCB) with a minimum of four layers is recommended for all designs utilizing the FS453.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE Figure 11: Recommended Pow er Filter Netw orks 9.1.2 Ground Connect the analog and digital grounds of the FS453 to separate ground planes. This will insure that electrical noise from the digital ground does not pollute the analog ground.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 9.2.2 Video Inputs The digital pixel data and the pixel clock of t he FS453 may toggle at speeds up to 150 MHz (depending on input mode). It is critical that the traces used for these signals be k ept as short as possible.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 9.3.1.2 Suggested Output Filter Netw ork Figure 12 below shows the suggested output filter net work for the FS453. Note that SDTV and HDTV use different values. Figure 12: Recommended Output Filter JANUA RY, 2005, VERSION 3.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE The recommended network shown in Figure 12 on page 33 will deliver robust video quality. It incorporates a source-terminating 75 Ohm resist or and a filter tuned for 37.5 Ohm impedance (assuming a matching 75 Ohm terminating resistor at the l oad).
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE graphics controller’s digital video data. The timing of t he variable pixel clock is critical; any disturbances to this signal will translate directly into noise on the video output.
FS453/4 AND FS455/6 DATA SHEET: HARDWA RE REFERENCE 9.4.3.1 Pseudo-master Mode In Pseudo-master Mode shown below, the FS453 has comp lete control of the gr aphics system clock, but relinquishes the video sync signals to the GCC. The GCC provides the FS453 with a complete complement of digital video signals at t he rate of the FS453 clock (CLKOUT).
