The LMK04832SEP EVM 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 2-1.
- Connect a voltage of 4.5 V to the VCC SMA connector or terminal block. The LMK04832-SEP and onboard VCXO operate at 3.3 V provided by the onboard TPS73801-SEP LDO and LP5900 LDO, respectively.
- Connect a reference clock to the CLKin1* port from a signal generator or other source. Use 122.88 MHz for the default configuration.
- Connect a USB A Plug-B Micro Plug cable to a PC and the USB connector (J45) at EVM.
- Program the device with TICS Pro. TICS Pro is available for download at: http://www.ti.com/tool/ticspro-sw.
- Select LMK04832-SEP from the Select Device menu. Click Select Device → Clock Generator/Jitter Cleaner (Dual Loop).
- Select USB2ANY mode from the Communication Setup window. To access this, select USB communications → Interface. Click Identify to confirm that the PC to USB communication is working. A blinking green LED on the USB2ANY indicates the PC is able to communicate through the USB2ANY.
- 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.
- Press Ctrl+L 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 (see Section 11.3).
- Measurements may be made at an active CLKout port through the SMA connector.
