The MAX9626 EV kit provides SMA connectors at the
inputs to accept differential signals at IN+ and IN-. At the
output, SMA connectors OUT+ and OUT- are provided to
monitor the output signal. By default, OUT- is connected
to GND through resistor R17.
The EV kit provides placeholders (R3 and R4) to
terminate IN+ and IN-, respectively. Install resistors
on R3 and R4 if input termination is required. When
internal terminations are used, remove external termination
resistors R6 and R7.
Jumper JU1 controls the shutdown mode (SHDB) of
the device. When SHDB is pulled low, the device is
disabled. When the SHDB pin is pulled high, the device
is enabled. See Table 1 for JU1 jumper selection.
The output common mode can be easily set by
applying a voltage at the VOCM input PCB pad on the EV
kit, thus eliminating the need for a coupling transformer
or AC-coupling capacitors. An SMA connector is also
provided at VOCM to allow a high-frequency signal to
characterize the bandwidth of the VOCM path. In this
case, a resistor must be installed at R16 and capacitors
C3, C6, and C7 should be removed.
