  • Page 2 The software components run on a USB-equipped PC and are described in detail in Section “5. Software Guide” The Si5xx-PROG-EVB evaluation board can be used to evaluate the Si514, Si570, Si571, Si598, and Si599 I programmable XOs or VCXOs as shown in Table 1. The Si514-PROG-EVB evaluation board can be used to evaluate the Si514 I C-programmable XO as shown in Table 1.

  • Page 3: Quick Start

    1.1. Quick Start 1. Install an Si514, Si570, Si571, Si598, or Si599 device on the board (Si514-PROG-EVB comes with an Si514 preinstalled; the Si570-PROG-EVB also comes with an Si570 installed). 2. Verify that the jumper settings are correct. 3. Connect the USB cable from the EVB to the host PC.
