VersaClock 6E - 5P49V60, 5P49V6965 and 5P49V6975 Evaluation Board User Guide Introduction The evaluation board is designed to help the customer evaluate the 5P49V60, 5P49V6965 and 5P49V6975 devices. 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. The 5P49V60 and 5P49V6965 use an external crystal, and the 5P49V6975 has an integrated crystal. The devices are pin-compatible and can use the same board. Board Overview Use Figure 1 and Table 1 to identify: power supply jacks, USB connector, input and output frequency SMA connectors. Figure 1.

Board Power Supply The voltage for each of the four V pins can be selected with jumpers. In the 5-pin configuration, the center pin is connected to the DDO V pin on the device. The four pins around it are connected to different power sources. A jumper connects the V pin to a power DDO DDO source of choice. 2018 Integrated Device Technology, Inc. 2 February 12, 2018
