4.1.3.3 Side Band Interface (SBI)

Side band interface can be evaluated using controls available on the output page. There are two methods that can be used to enable SBI on the LMKDB1104.

  1. Automated: When using on-board USB power supply option on the EVM, clicking once on the Enable SBI Control button configures the LMKDB1104 into SBI mode.
  2. Manual: This method requires to set the Set Pin SBI_EN to High followed with a power cycle on the board. This is needed when using external supply option or when not using the Enable SBI Control button. SBI is enabled on LMKDB1104 after the restart.

After using any of the methods above, press Read SBI_EN to verify status of SBI mode on the device. Use check boxes for CLK0 through CLK3 to enable (checked) or disable (unchecked) the desired outputs. Once selected, click on SBI Latch Enable to load data into shift register.
