Page 5: Introduction
HD video over long distances of existing coaxial or twisted-pair cable networks or allow the use of less expensive RG-59/UTP cable in long distance installations. SM08 can accept either twisted pair or coaxial cable inputs (build option) and supports the following HD aCVi formats: 720p-25/30/50/59/60Hz, 1080p-24/25/29/30Hz, 1080i-50/59/60Hz as well as NTSC-M/PAL and NTSC-960H and PAL-960H video standards. -
Page 6: Connecting Up The Module
Once connected, the green LED, ‘Program OK’, should light, indicating the FPGA has been correctly programmed. See Figure 2. SM08 can accept either coaxial or twisted pair cable inputs, but this is a build option for the board and needs to be specified at the time of order. -

Page 10: Circuit Description
SingMai Electronics 4. Circuit description Figures 5-13 show the schematics for the SM08. The component overlay for the PCB is shown in Appendix A. Below is a brief technical description of the SM08 module. Sheet 1. J1 is the 5VDC power input connector to the SM08 module. The 5VDC is protected from over- voltage and reverse polarity inputs by D1, D2 and resettable fuse, F1. - Page 11 U8 is compared with an FPGA internally generated checksum. If the two do not match the SM08 module is shut down. This means that even if the bit stream of the FPGA/EEPROM is captured the PT51 IP core will not run without U8 being fitted.

LVDS outputs, together with an LVDS clock, to the HD-SDI/SDI serialiser IC, U17, which converts these five data signals into one 1.485GHz/270MHz, HD-SDI/SDI compatible, output (J4). Components L5 and R61 are used to improve the return loss. Figure 5 SM08 schematics - sheet 1. SM08 User Manual Revision 0.2 Page 12 of 36... -

Page 21: Re-Programming The Fpga
Install and open the Quartus programmer. The screen should look similar to Figure 15. The new FPGA image will be sent as a file called SM08.pof. Set the programming mode to ‘Active Serial Programming’. If everything is OK the programmer should recognize the serial EEPROM (shown as EPCS4). -
