Manufacturer:XILINX Description:The analog outputs are designed to directly drive a dual 50 or 75 ohm load transmission system as shown. The source impedances of the SPT1018 outputs are high impedance current sinks. The load impedance (R L) must be 25 or 37.5 ohms to attain standard RS-343-A video levels. Any deviation from this impedance will affect the resulting video output levels proportionally. As with the data interface, it is important that the analog transmission lines have matched impedance throughout, including connectors and transitions between printed wiring and coaxial cable. The combination of matched source termination resistor RS and load terminator RL minimizes reflections of both forward and reverse travel- ing waves in the analog transmission system. The return path for analog output current is VCC which is connected to the source termination resistor RS. |
