4.1 Evaluation Setup

Default EVM configuration is operated in SPI mode with LDO bypassed. Setup the connection as shown in Figure 2-1. Run TICS Pro evaluation software and follow these steps to start the program. Same operation applies to the other two EVM variants.

  1. Go to Select Device → PLL + VCO → LMX2624-SP.
