Detailed Description
Connecting CML Outputs to 50
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
to ground.
Terminating Unused Outputs
The MAX3781 EV kit has 100
differential resistors
placed across all outputs. These resistors must be
removed before connecting the outputs to a 50
oscil-
loscope. For best performance, keep all outputs termi-
nated, either to a 50
measurement device or to the
100
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
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.
