SMA connectors for

2 differential input clocks

GENERAL DESCRIPTION

This user guide describes the two evaluation boards for

evaluating the HMC6832 fully differential output buffer.

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.

GETTING STARTED

For convenience, many of the jumpers are preinstalled on

the evaluation boards as listed in Table 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.

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.

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.

SETTING UP SIGNAL CONNECTIONS

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:

• To select Input 0, tie J3 to ground.

• To select Input 1, tie J3 to VDD.

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

To use an external power supply, such as for current measure-

ments, 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).
