2.1

Quick Start Description

The LMK04832EVM-CVAL allows full verification of the device functionality and performance
specifications. To quickly set up and operate the board with basic equipment, refer to the quick start
procedure below and test setup shown in

Figure 1

1. Connect a voltage of

4.5

volts to the V

SMA connector or terminal block. The

LMK04832-SP

and on-

board VCXO operate at 3.3 V provided by the onboard

TPS7A4501-SP

LDO.

2. Connect a reference clock to the CLKin1* port from a signal generator or other source. Use

122.88

MHz

for default configuration.

3. Connect USB2ANY to a PC and the EVM.

4. Program the device with TICS Pro. TICS Pro is available for download at:

http://www.ti.com/tool/ticspro-sw

a. Select LMK04832-SP from the

Select Device

Menu. Click

Select Device

→

Clock Generator/Jitter

Cleaner (Dual Loop)

b. Select

USB2ANY mode

from the Communication Setup window. To access this, select

USB

communications

→

Interface

. Confirm that the PC to USB communication is working by clicking on

Identify.

A blinking green LED on the USB2ANY indicates the PC is able to communicate through

the USB2ANY.

c. Select a default mode from the

Default configuration

Menu. For the quick start use,

CLKin1 122.88

MHz, OSCin 122.88 MHz, VCO1 2949.12 MHz

Ctrl+L

must be pressed at least once to load all registers. Alternatively, click the

USB

communications

→

Write All Registers

menu, the

Write All Registers

button on toolbar, or the

Raw

Registers

page shown in

Section A.3

5. Measurements may be made at an active CLKout port through the SMA connector.
