Both evaluation boards, EV1HMC6832ALP5L and EV2HMC6832ALP5L, allow access to all HMC6832 input/outputs via SMAs. The EV1HMC6832ALP5L is configured for the LVPECL version of the product whereas the EV2HMC6832ALP5L is configured for LVDS. Each board has an on-board low dropout (LDO) regulator for 2.5 V/3.3 V operation that can be disabled to use an external supply. Each board has matched RF differential traces for testing output to output channel skew. For full specifications on the HMC6832, see the product data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board. The evaluation board schematics and the HMC6832 data sheet are available on the HMC6832 product page. 14294-001 PHOTOGRAPH OF EV1HMC6832ALP5L Figure 1.

The jumper installation is dependent on the version of the evaluation board, EV1HMC6832ALP5L or EV2HMC6832ALP5L. Prior to powering on the evaluation board, it is important to verify the jumper configuration against Table 1 and Figure 3 for the physical locations of the jumpers and test points. There are two ac-coupled inputs to choose from, Input 0 or Input 1, via the IN_SEL pin of the HMC6832. The input is determined by J3 on the evaluation board. A signal generator can be connected to either or both of these inputs and the user can select between them as follows: POWERING THE EVALUATION BOARD • • It is important to decide whether to use the on-board voltage regulator or an external power supply because the jumper configurations vary accordingly. Refer to Table 1 for the required jumper configurations. Connect the output(s) of interest to either an oscilloscope or a spectrum analyzer for observation and evaluation (see Figure 4). BYPASSING THE 5 V LDO VOLTAGE REGULATOR If using the on-board regulator, apply 5 V to TP3 and ground either TP1 or TP4. Figure 4 provides an example of this scheme. In this scenario, install J8 but do not install J7. J6 determines the output voltage of the regulator and installing J9 allows observation of the regulator output voltage at TP2. Refer to Table 1 for additional information about J6 and J9. VDD 50kΩ To select Input 0, tie J3 to ground. To select Input 1, tie J3 to VDD. To use an external power supply, such as for current measurements, bypass the on-board voltage regulator. To bypass the regulator, reconfigure the jumpers by installing J7 and not installing J8. An external supply of either 2.5 V (LVDS or LVPECL) or 3.3 V (LVPECL only) can then be supplied to TP2 (see Table 2).

Table 1. Jumper Settings Jumper Number J3 Installed As needed, depending on input desired. J5 Function Input level for IN_SEL pin. GND selects Input0 and DUT_VCC selects Input1. Determines LVPECL/LVDS mode. J6 Determines the regulator supply. Regulator supplies 2.5 V, assuming it is enabled (J7 not installed) and 5 V is supplied to TP3. J7 Enables or disables the regulator output. Connects or disconnects the regulator output to the HMC6832 device. 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. Analog Devices, Inc., use only. Disables regulator output. J8 J9 J30 Sets CONFIG pin to proper configuration mode (LVPECL/LVDS). Connects the regulator output to the device. 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. Do not install. 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. Preinstalled on Evaluation Board No Yes Yes No Disconnects the regulator output and the device. Power cannot be applied or observed at TP2. Yes Analog Devices use only. No Yes Table 2. Test Points Test Point Number TP1 TP2 TP3 TP4 Function Ground connection. 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. 5 V supply for the on-board regulator. Ground connection.
