2 EVM Quick Start

Table 2-1 describes the default jumper positions for the EVM to power the device from a single 12V supply provided to VIN4. In positional information about jumpers, adjacent designator means the jumper is placed adjacent to the designator. Opposite designator means the jumper is placed opposite of the designator.

To begin using the LMK5C33216A, follow the steps below.

Hardware Setup

1. Verify the EVM default jumper and DIP switch settings shown in Figure 1-1.
2. Connect the 12V external power DC power supply (1A limit) to:
   1. VIN4 and GND terminals on header J500 (pins 4and 5, see Figure 3-2.)
3. Connect references:
   1. 25MHz reference clock to IN0_P/N and/or,
   2. 25MHz reference clock to IN1_P/N
4. Connect the USB cable to the USB port at J41.

Software Setup

1. If not already installed, then install TICS Pro software from TI website: TICS Pro Software
2. If the MATLAB R2015b (9.0)* 64-bit runtime is not already installed, download and install from MathWorks website. While optional for programming and evaluating the default profile settings, the Matlab Runtime is necessary for any application that needs to modify the DPLL loop filter settings. See Matlab Runtime.
3. Start TICS Pro software.
4. Select the LMK5C33216A profile from Select Device → Network Synchronizer Clock (Digital PLLs) → LMK5C33216A.
5. Confirm communications with the board by:
   1. Click USB communications from the menu bar.
   2. Click Interface to launch the Communication Setup pop-up window.
   3. Check these fields in the Communication Setup pop-up window:
      1. Make sure USB2ANY is selected as the interface.
      2. In case of multiple USB2ANY, select desired interface. If a USB2ANY is currently in use in another TICS Pro, then users must release that interface by changing the interface setting to DemoMode.
      3. Click Identify to blink LED shown in Figure 2-1. This confirms you are connected to the board you expect. Be aware that USB2ANY devices connected to the PC but not attached to by a TICS Pro instance can blink at a slow rate of 1 second on, 1 second off continuously. After clicking the Identify button, the LED flashes quickly at about 0.5 second on, 0.5 second off for about 5 seconds.

Program the LMK5C33216A

1. Toggle the switch S5 (PDN/RESET).
2. Program all the registers:
   1. Press the Write All Regs button in toolbar,
   2. Select USB Communications in the menu bar, then select Write All Registers, or
   3. Press Ctrl + L.
3. Check the current consumption (maximum 1.3A).
4. Check LMK5C33216A Status as shown in Figure 2-2.
   1. Go to the Status page of the GUI.
   2. Click Read Status Bits.
   3. Make sure to clear the latched bits. To clear latched bits:
      1. Press the Clear Latched Bits button.
      2. Select Read Status Bits.
   4. Wait to confirm the change. This can take some time for the DPLL status bits to reflect lock.
