2 EVM Quick Start

Table 2-1 describes the default jumper positions for the EVM to power the device from a single 4.5 V supply provided to VIN1. In positional information about jumpers, adj des means jumper is placed adjacent to designator. Opp des means jumper is placed opposite designator.

To begin using the LMK5C33216, follow the steps below.

Hardware Setup

1. Verify the EVM default jumper and DIP switch settings shown in Table 3-1.
2. Connect Power, +4.5 V from an external DC power supply (2-A limit), see Figure 3-2.
   1. To VIN1 & GND terminals on header J1 (pins 1 and 4), or
   2. To VIN1 SMA connector J2.
3. Connect references.
   1. 156.25 MHz reference clock to IN0_P/N and/or,
   2. 10 MHz reference clock to IN1_P/N
4. Connect USB cable to USB port at J41.

Software Setup

1. If not already installed, install TICS Pro software from TI website: http://ti.com/tool/TICSPRO-SW
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 https://www.mathworks.com/products/compiler/matlab-runtime.html
3. Start TICS Pro software
4. Select the LMK5C33216 profile from Select Device → Network Synchronizer Clock (Digital PLLs) → LMK5C33216
5. Confirm communications with board by
   1. From the menu bar, click USB communications.
   2. Click Interface
   3. In Communication Setup pop-up window.
      1. Ensure 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, you must release that interface by changing its interface setting to DemoMode
      3. Click identify to blink LED illustrated in Figure 2-1. This confirms you are connected to the board you expect.

Program LMK5C33216

1. Toggle switch S5 (PDN/RESET).
2. Program all the registers by…
   1. Pressing Write All Regs button in toolbar
   2. From the menu bar click USB Communications then click Write All Registers, or
   3. Pressing Ctrl + L.
3. Current consumption should be approximately 1.15 A.
4. Check LMK5C33216 Status
   1. Status Page of GUI
   2. Click Read Status Bits
   3. To clear latched bits.
      1. Press Clear Latched Bits button
      2. Read Status Bits
   4. It may take some time for the DPLL status bits to reflect lock.
