Equalizer and LMH0001 SMPTE 259M / 344M Cable Driver.
The LMH0026 inputs are LVPECL compatible. The LMH0026
has a wide input common mode range and in most cases the
input should be DC coupled. For DC coupling, the inputs must
be kept within the common mode range specified in
trical
coupled interface between the LMH0074 cable equalizer and
the LMH0026. The LMH0074 output common mode voltage
and voltage swing are within the range of the input common
mode voltage and voltage swing of the LMH0026. All that is

required is a 100Ω differential termination as shown. The re-
sistor should be placed as close to the LMH0026 input as
possible. If desired, this network may be terminated with two
50Ω resisters and a center tap capacitor to ground in place of
the single 100Ω resistor.
The LMH0026 outputs are LVPECL compatible. SDO is the
primary data output and SCO/SDO2 is a second output that
may be set as the serial clock or a second data output. Both
outputs are always active. The LMH0026 output should be
