JUMPER CONFIGURATIONS

Refer to Figure 3 for jumper and test point locations on the board.
Table 1. Jumper Settings
Jumper
Number Function
J3 Input level for IN_SEL pin. GND
selects Input0 and DUT_VCC selects
Input1.
J5 Determines LVPECL/LVDS mode.
J6 Determines the regulator supply.
J7 Enables or disables the regulator
output.
J8 Connects or disconnects the
regulator output to the
device.
J9 Determines the function of TP2 to
observe the regulator output or to
apply power to the
device, depending on the
installation status of J8.
J30 Analog Devices, Inc., use only.
Table 2. Test Points
Test Point
Number Function
TP1 Ground connection.
TP2 When J8 and J9 are installed, TP2 observes the regulator output. When J9 is installed and J8 is not installed, TP2
supplies power (2.5 V or 3.3 V) to the HMC6832.
TP3 5 V supply for the on-board regulator.
TP4 Ground connection.

Installed
As needed, depending on input
desired.
Sets CONFIG pin to proper
configuration mode (LVPECL/LVDS).
Regulator supplies 2.5 V, assuming
it is enabled (J7 not installed) and 5
V is supplied to TP3.
Disables regulator output.
Connects the regulator output to
HMC6832 the device.
When J8 is installed, the regulator
output can be observed at TP2.

Uninstalled
If not installed, default is
Input0 as IN_SEL has an
internal pull-down
Sets HMC6832 to LVDS
mode due to internal
pull-up on the device.
Regulator supplies 3.3 V,
assuming it is enabled (J7
not installed) and 5 V is
supplied to TP3.
Enables regulator output.
Disconnects the
regulator output and the
device.
Power cannot be applied
or observed at TP2.
