VersaClock 3S - 5P35021 Evaluation Board USER GUIDE Introduction The evaluation board is designed to help the customer evaluate the 5P35021, the latest addition to the family of programmable devices in IDT s Timing portfolio. When the board is connected to a PC running IDT Timing Commander Software through USB, the device can be configured and programmed to generate different combinations of frequencies. Board Overview Use Figure 1 and Table 1 to identify: power supply jacks, USB connector, input and output frequency SMA connectors.
