DC-coupled inputs must be kept within the specified common-mode range. OUTPUT INTERFACING The DS30BA101 uses current mode outputs. Single-ended output levels are 800 mVP-P into 75Ω AC-coupled coaxial cable with an RVO resistor of 750Ω, or 400 mVP-P (800 mVP-P differential) into 100Ω differential cable with an RVO resistor of 953Ω. The output voltage level is controlled by the value of the RVO resistor connected between the RVO pin and VCC. The RVO resistor should be placed as close as possible to the RVO pin. In addition, the copper in the plane layers below the RVO network should be removed to minimize parasitic capacitance. Figure 2 and Figure 3 show the typical configurations for differential output and single-ended output, respectively. For single-ended output, the unused output must be properly terminated as shown. APPLICATION INFORMATION CABLE EXTENDER APPLICATION The DS30BA101 together with the DS30EA101 form a cable extender chipset optimized for extending serial data streams from serializer/deseralizer (SerDes) pairs and FPGAs over 100Ω differential cables and 75Ω coaxial cables. Setting the correct DS30BA101 output amplitude and proper cable termination are essential for optimal operation. Figure 2 shows the recommended chipset configuration for 100Ω differential cable and Figure 3 shows the recommended chipset configuration for 75Ω coaxial cable.
