• Manufacturer Part Number: lmh0036sq
• Description: Sd Sdi Reclocker With 4 1 Input Multiplexer
• Manufacturer: National Semiconductor Corporation

The 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 al-
ways active. The LMH0036 output should be DC coupled to
the input of the receiving device as long as the common mode
ranges of both devices are compatible.
Figure 6 shows an example of a DC coupled interface be-
tween the LMH0036 and LMH0001 cable driver. All that is
required is a 100Ω differential termination as shown. The re-

sistor should be placed as close to the LMH0302 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 LMH0036 has multiple ground connections, however; the
primary ground connection is through the large exposed DAP.
The DAP must be connected to ground for proper operation
of the LMH0036.
