J3 Input level for IN_SEL pin. GND
selects Input0 and DUT_VCC selects
Input1.
As needed, depending on input
desired.
If not installed, default is
Input0 as IN_SEL has an
internal pull-down
No
J5 Determines LVPECL/LVDS mode. Sets CONFIG pin to proper
configuration mode (LVPECL/LVDS). Sets HMC6832 to LVDS
mode due to internal
pull-up on the device.
Yes
J6 Determines the regulator supply. Regulator supplies 2.5 V, assuming
it is enabled (J7 not installed) and 5
V is supplied to TP3.
Regulator supplies 3.3 V,
assuming it is enabled (J7
not installed) and 5 V is
supplied to TP3.
Yes
J7 Enables or disables the regulator
output.
Disables regulator output. Enables regulator output. No
J8 Connects or disconnects the
regulator output to the HMC6832
device.
Connects the regulator output to
the device.
Disconnects the
regulator output and the
device.
Yes
J9 Determines the function of TP2 to
observe the regulator output or to
apply power to the HMC6832
device, depending on the
installation status of J8.
When J8 is installed, the regulator
output can be observed at TP2.
When J8 is not installed, power can
be applied (2.5 V or 3.3 V) via TP2.
Power cannot be applied
or observed at TP2. Yes
J30 Analog Devices, Inc., use only. Do not install. Analog Devices use only. No
