2 / 5 page Detailed Description Connecting CML Outputs to 50 Ω Oscilloscopes CML outputs have a common-mode voltage near VCC. To avoid changing this optimum common-mode volt- age, all CML outputs are AC-coupled on-board with 0.1µF capacitors. The CML outputs should not be con- nected directly through 50 Ω to ground. Terminating Unused Outputs The MAX3781 EV kit has 100 Ω differential resistors placed across all outputs. These resistors must be removed before connecting the outputs to a 50 Ω oscil- loscope. For best performance, keep all outputs termi- nated, either to a 50 Ω measurement device or to the 100 Ω differential resistor. Control Lines Jumpers JU1, JU2, and JU3 are provided to set the operating mode of the MAX3781. Shorting these jumpers pulls the corresponding TTL control line to a logical zero. All TTL control lines are internally pulled high through 15k Ω resistors. See Table 1 for more infor- mation regarding setting operating modes. Exposed-Pad Package The exposed paddle (EP) 48-pin TQFP has features that provide a very low thermal resistance path for heat removal from the IC. The paddle is electrical ground on the MAX3781 and should be soldered to the circuit board for proper thermal and electrical performance.
